Router Authentication

Does all IOS support the above? Do I need to look for the feature set that support it? Which version and above uses this command "crypto key pubkey-chain dss" and which version and below uses the old command "crypto public-key"

All versions and all feature sets of IOS support router authentication.

Re: Router Authentication

Just found out that Cisco took out the CET feature from 12.1 onwards.

I've about ten 2500 routers that only support the classic crypto which is the Cisco Encryption Technology (CET). Those routers are running IOS version 11.2(18)P. The new core router is a 3725 with IOS Advanced IP Services 12.4(2)XA1 which does not have CET.

I cannot upgrade the IOS of 2500 routers as they do not have enough memory to use IPSEC.

What other alternatives do I have based on what I have? As long as I can encrypt the line is good enough.

Appreciate to all who knows how and/or done this before.

thanks

Cheers,

Re: Router Authentication

The command "crypto key pubkey-chain dss" was introduced in IOS version 11.2.

Please rate if this helps.

I'm aware of the command but Cisco took out the dss parameter from 12.1 onwards. Now I can find rsa only.

Thanks.
