Re: sup 720 sso rpr

The guy at TAC told me I needed NSF/SSO (see NSF section of config guide). Once you have it configured, it would be smart to conduct a test of the failover. Obviously you would probably want to do this during a planned outage just in case.

Note: Remember to add the 'NSF' statement to your route processes.

Re: sup 720 sso rpr

Thanks for your reply.

In my case I use statics routes, but why not rpr+.

Hi Eric,

Have a look at this and you will get a clear picture of difference between RPR , RPR+ and SSO
