Hi,

Not sure exactly what is your question, but if apply this command:

no neighbor 192.168.12.1 route-map prepend-AS in

This will remove your BGP neighbor and you will loose connectivity to it.

Also, once this command is applied, all the other commands are not effective until you peer with this neighbor again.

In the config, these commands are being shown:

neighbor 192.168.12.1 remote-as 111

neighbor 192.168.12.1 timers 5 15

neighbor 192.168.12.1 route-map prepend-AS in

neighbor 192.168.12.1 route-map PCL-KIR-Out out

I want to remove only third line (no neighbor 192.168.12.1 route-map prepend-AS in)

Still it will remove the neighour..

Please confirm.

Re: BGP Concern

Hi Ray,

If this is the Config that you have, then removing only the 3rd line will not remove the neighbor.

The association with the neighbor will stay as it is.

Sure?

Yes we are sure. That command will take out the inbound route map for the neighbor. But it will not remove the neighbor.

Re: BGP Concern

Hi Ray,

Yes, as Rick says, we are sure. The first line in the Config where we mention the ip address and the remote-as number is the command which creates the neighbor association.

Rick, please correct me if I am wrong.
