Elmer, The way I read your config. You have enabled a single interface with EIGRP routing, interface loopback17 of network 192.168.199.0/24.
You are redistributing all of EIGRP into BGP which only includes this one network. You are aggregating 192.168.192.0 255.255.248.0. The aggregate address needs a minimum of one network in the aggregate address range to advertise the supernet and more specific underlying routes. The BGP table is exactly right as far as I can tell. The only networks that should appear are the networks redistributed from EIGRP, 192.169.199.0/24, and the aggregate, 192.168.192.0/21, which is using the previous /24 network for its very existence. You must enter EACH of the loopbacks under the BGP process using 'network 192.168.192.0 mask 255.255.255.0', 'network 192.168.193.0 mask 255.255.255.0'..... The mask statement is not necessary in this case, I just always use it for consistency. It is a personal preference. The mask statement is only necessary for networks outside their classful boundary. The other alternative is to include all of the loopbacks under the EIGRP process and have them redistributed into BGP which you already have setup, but currently you are only redistributing a single /24. If you want them all to appear, you need to either enter them under the BGP process with a network statement or redistribute them from EIGRP. The route-map you have included in the configs looks like you are planning on only advertising a subset of the more specific /24 routes. You should look at the suppress-map option under the aggregate address command as well as distribute list under the interface or neighbor statement. All three of these would accomplish the same result. -----Original Message----- From: cebuano [mailto:[EMAIL PROTECTED]] Sent: Sunday, September 29, 2002 11:34 PM To: [EMAIL PROTECTED] Subject: BGP Aggregation in IOS 12.2 [7:54528] Hi all. Has 12.2 changed in that when you do an "aggregate-address" the configured router only shows the aggregate route and not include the more-specific ( or aggregatED ) routes? Here's what I got... This config is "supposed" to allow me to advertise both the aggregate and more-specific routes. But if this has changed then i'll have to think of another solution... Thanks.
