Personally, the cleanest way I've been able to accomplish changing this in regard to OSPF, logging and authentication on Cisco's is to suck down the running config, make the changes in your editor of choice, push it back up to startup-config and schedule a reboot. iBGP is much easier to make the changes as you outline.this is my fear. which is why i asked. pushing out new configs (the canonic config is on disk, not the router [0]) and setting a reload of a bunch of routers at time t0 does not give me warm fuzzies about what the world will be like at time tn (n > 0). but i may have to take that path. i am hoping folk will give me a magic pill. after all, any group with such a deep understanding of how to deal with the world's social ills must know a bit of router magic <smirk>.
You may need to change your BGP router-id to match if you set it explicitly, which *may* alter path selection (a long way down the tree I admit). Another nasty is if you run TE and use the old Loopback as your TE-ID, even with IS-IS. Plus of course, your zone/hosts file for managing/polling these nodes in the first place :-) -- Ian Dickinson Development Engineer PIPEX ian.dickinson () pipex net http://www.pipex.net This e-mail is subject to: http://www.pipex.net/disclaimer.html
