Recently one of our peering points had to renumber from a /22 to a /21 - Unfortunately they had to change the whole range as the neighbouring /22 was already assigned.

Usually in Cisco land it would be a hassle to have to change BGP config as I have 150 peers on that subnet currently. I would need to strip out all the old config and replace with new ranges, including passwords, options, etc etc

However on my Juniper router I simply went under the BGP process and said:
Code:
rename neighbor [old IP] neighbor [new IP]


All the config underneath the neighbor statement stays exactly the same. Did the above for 150 peers (thanks Excel) updated filters and committed the changes.

Took about 10 minutes of real work :)

Dang. I tried to get some Juniper pricing a while back before we purchased some new 7606S's and never heard back from them :(
