  1. is there something that I have to take into consideration related to endpoints or other VCS (this is a cluster) before you download a new certificate?

  2. communication between endpoints will affect?

  Hello

  If you are looking to get your certificates signed by yourself or a public certification authority I would first make sure that your servers have host names and configured DNS records. In addition, if you plan to use the edge of the collaboration (MRA) you should take a look at the additional without required for this:

  You shouldn't have issues with endpoints being affected, in my experience, the certificates have affected only edge of collaboration.

• Cisco IOS Software Internet Key Exchange vulnerability Enquiry

  Products affected

  Cisco IOS devices are vulnerable when you run a software image of an affected version of the Cisco IOS software that does not support the IKE version 2 (IKEv2) and is configured to use IKE version 1 (IKEv1).

• Cisco IOS it helps 3rd party certificate

  Hello

  Can I use a 3rd party such as verisign, on Cisco IOS CA? All I can see on cisco.com is a self-signed certificate to the router.

  Thank you

  -santo-

  Santo,

  That's fair enough. A key piece of information to ensure that customers understand that a private PKI gateway is (for the purposes of deployment for example GETVPN) as secure as provided by the third party.

  Private PKI is not based on self-signed certificates free - only the root CA will take something like that :-)

  That being said, for reliability and flexibility I really suggest CA (ser, CRL, OCSP, public/private key backup) to store files on the external storage to the router.

  Takeway key which is a private PKI properly managed solution for deployments like DMVPN/GETVPN others is as secure as external 3rd party services (and often the time order of magnitude cheaper).

• Cisco IOS DHCP Server + classless static routes on DHCP clients

  Hi, I tried to find if it is possible to add the ability for static routes to DHCP clients on the Cisco IOS DHCP configuration mode. I'm looking to add a parameters as defined in RFC 3442, like this one, located on the ISC DHCPd server:

  Global settings:

  121 = integer table 8 code option rfc3442-classless-static-routes;

  ms-classless-static-routes option code 249 = integer table 8;

  And for the subnet declaration:

  option rfc3442-classless-static-routes 24, 192, 168, 30, 192, 168, 10, 1;

  option 24 ms-classless-static-routes, 192, 168, 30, 92, 168, 10, 1;

  Is this possible?

  Thank you!

  Vitor

  Yes, the fun part it is to convert it into a format IOS will accept.  You can try:

  IP dhcp pool 0

  option 121 24.192.168.30 ip 192.168.10.1

  option 249 ip 24.192.168.30 92.168.10.1

  If this does not work, change the "intellectual property" for "hex" and each of your decimal byte converted to hexadecimal.

• Installation of on IOS SSL certificates

  Having a problem with an SSL certificate (DigiCert) on a Cisco 2811 running IOS 124 - 24.T4.

  I can get the certificates, intermediate and certificates of server installed fine unsing the a trustpoint created. Web ssl site works very well for IE browsers, and other types of browsers get errors. When I do a verification of the SSL certificate it shows that the "the server does not send the certificate requires intermediary" (see attachment). I feel that I have followed is available as well. Any suggestion is appreciated.

  It's the best information I could find to follow. They are specifically for Go-Daddy certs, but I think it would be the same process for all.

  http://bytesolutions.com/support/knowledgebase/KB_Viewer/Smid/622/articleid/21/reftab/195/t/installing-GoDaddy-SSL-certificates-on-a-Cisco-IOS-router-using-CLI.aspx

  Thank you

  BR

  Hello

  If you have several CA certificates, you must authenticate the trustpoint containing the CERT of identity using the immediate intermediate cert and then use other trustpoints to import the other CA certs one by one.

  So, basically, we need to follow the following configuration to import the CA 3 certificate and the certificate of identity on the router:

  1.  Create root trustpoint >> >> Crypto ca trustpoint root >> Enrollment terminal >> >> chain-validation stop >> >> revocation-check none >> >> Crypto ca authenticate root >> (this will prompt to paste in the PEM/base64 of the Root CA certificate) >> Quit after you paste the Root CA certificate. >> >> >> 2.  Create intermediate trustpoint for the primary intermediate certificate >> >> crypto ca trustpoint intermediate-primary >> enrollment terminal >> >> chain-validation continue root >> >> revocation-check none >> >> crypto ca authenticate intermediate-primary >> (this will prompt to paste in the PEM/base64 of the Primary Intermediate CA certificate) >> Quit after you paste the intermediate primary certificate. >> >> >> 3.  Create intermediate trustpoint for the secondary intermediate certificate >> >> crypto ca trustpoint intermediate-secondary >> enrollment terminal >> keypair >> chain-validation continue intermediate-primary >> >> crypto ca authenticate intermediate-secondary >> (this will prompt to paste in the PEM/base64 of the Secondary Intermediate CA certificate) >> Quit after you paste the intermediate secondary certificate. >> >> 4.  Import the IDentity certificate >> >> crypto ca import intermediate-secondary certificate >> (paste the ID certificate PEM/base64 here) 

• Cisco IOS router 837 - configure DDNS / dynamic DNS

  I have an Internet, connected to my Cisco router link. The package that I subscribed comes with a dynamic IP address. I said me, if I need remote access in the Cisco router, I need to enable the DDNS function. Is this possible on a Cisco router? I have been informed that this feature is not supported. Please help me

  Hi Bro

  Yes, Cisco ASA and Cisco IOS router supported DDNS. Just make sure you have the right version of IOS, which you could refer to this URL of Cisco http://www.cisco.com/en/US/docs/ios/12_3/12_3y/12_3ya8/gt_ddns.html#wp1202953.

  Please refer to the config below made with dyndns.org.

  !

  hostname INT-RTR1
  !
  IP domain name dyndns.org
  8.8.8.8 IP name-server
  !
  IP ddns update DynDNS method

  Note: hostname = INT - RTR1.dyndns.org was the host added/registered in the dyndns.org site.

  Note: Press Ctrl + V, then just type the symbol? When to add the CLI adds http://___ above.

• Cisco IOS CA

  Team,

  I use software Cisco IOS XE, Version 03.15.00.S - Standard Support version Cisco IOS software, software of CSR1000V (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 15.5 (2) S, (fc3) SOFTWARE VERSION to support my Cisco IOS CA.

  In short, I am trying to support a FlexVPN - client VPN Win7 according to document tac 115907 id

  In this document, he says that OpenSSL CA is used but a Cisco IOS CA can also be used. In tests I am at a point where my certificates do not match the example:

  The example document TAC:

  X509v3 extensions:
  X509v3 Key use: F0000000
  Digital signature

  Non-repudiation
  Encryption key

  Data encryption

  My version of laboratory:

  X509v3 extensions:
  X509v3 Key use: A0000000

  How can question - I get these replacement using the IOS Cisco CA extensions?

  I used the Microsoft certification authority (Windows 2003 server).
  Cisco VPN client used eTokenPRO Aladdin as a certificate store.

  Certificate of MSW CA registration and implementation in eToken ran OK
  Customer VPN Cisco doesn't have a problem with the cooperation of eToken.
  Certificate of registration of Cisco2821 MSW ca ran okay too.

  Cisco 2821 configuration is standard. IOS version 12.4 (6).

  Hey guys, it's weird that the router is not find cert after IKE is the cert and validates, it is certainly not reason, but I would go ahead and set up the mapping of certificate on this router to force the client to associate with Group of IKE, for that matter, that you need to change your config a bit for use iskamp profiles :

  Hello Jeff,.

  We were also quite surprised at the point where we realized, that our brand new 3850 did not support HSRP. This feature was introduced in a second version of the IOS - XE. Currently, we run 03.06.00.E on our WS-C3850-24 t and this version support HSRP.

  I don't understand absolutely, why Cisco released such a combo of software/switch isn't over.

  So, please try a newer version of the software.

• Remove the ISE server certificate EAP

  I installed the GoDaddy server certificates on all my 1.1.1 ISE nodes, but customers are still getting the error and accept certificates.  I would just remove EAP certificate and not use any certificate for EAP.

  Explain the problem more in detail. You try to use the comments or 802. 1 x. There are many protocols of authentication you want to use EAP. TLS and PEAP require the use of the cert. What you are trying to accomplish and what are the issues?
