Hello, Here is my simplified network layout (AS and IPs are made up for privacy): As you can see, we own one /20 and we have two locations connected to two different Internet peers. Network 1 is announcing the whole /20 and Network 2 is announcing...

Greetings, I have a question regarding summary-only option within the aggregate-address statements. Here is my layout: [INTERNET] | | [ISP 1] [ISP 2] | | [Loc 1]------...

For the sake of keeping my help request simple, I simplified my network layout quite a bid. The conceptional idea however is the same... We actually have several /20 and /21 IP prefixes that we break out based on usage. So, it's not uncommon to have...

The prefix is learned through OSPF and advertised because of a matching bgp network statement: network 1.1.4.0 mask 255.255.255.0 JB

coffee@0400, Thanks again for your help. I don't have any static Null routes in any of my routers. I think the Null routes are created by bgp in response to the aggregation... (see post above). The null routes become a black hole if my Metro etherne...
