Cisco Help
Hi, I have currently gotten some addtional IP addresses and was told by my ISP to configure the router accordingly. They also stated that they added the new IP's to my BGP session. I could show you a copy of my config if that helps.
Thank you for the help.
Thank you for the help.
Yes. Please post your config without passwords.

One addtional note is they stated:
non-portable netblock has been assigned to account number wcomw0h29113
Not sure if that makes a difference or not.

If I do the no IP route to the 208.255.99.120 I will loose those subnets?
They IP route x.x.x.x y.y.y.y is the new network?
The next hop would be my fast ethernet 0/1?
The IP prefix-list 2 seq 8 permit x.x.x.x/y do I place the new network?
And thank you for your help!!!

I'm rethinking my previous hints, and I think you want to leave the static routes as is (i.e. don't replace them with routes to null0).
The IP route x.x.x.x y.y.y.y would be the new network. The next hop can't be "Fast0/1" unless that address is natively bound there; you'll need to let us know how you're going to deploy the new subnet so we can fine-tune any particulars.
You'll have to place the new network in one prefix-list or the other. It'll be x.x.x.x/z, where z is the CIDR size of the network (just like your other prefix-list entries).

I just want to be able to recieve the IP's. SO I guess the next hop would be outbound correct?
As far the prefix This is the block I got: 65.209.71.236/30

If you just want to receive them, do the null route for now.
ASKER
Sorry now I'm confused. Were does the null route go?
ip route 65.209.71.236 255.255.255.252 null0 250
It goes nowhere, but makes the prefix exist in your RIB so that BGP will announce it and you will receive the traffic.

ok, so that is all I need to put in? or do I still need this part?
