Howdy folks,
I've been working through a few BGP scenarious and am
having a hard time removing the null route entries
generated when I create an agregate in bgp. I know
that one of the requirements is to have now null
routes (including those generated by routing
protocols). Removing with EIGRP and OSPF is simply a
matter of admin distance, but I'm not seeing a similar
option for the aggregate command.
What am I missing?
Sample config:
router bgp 300
no synchronization
bgp router-id 150.1.2.2
bgp log-neighbor-changes
network 136.1.23.0 mask 255.255.255.0
network 136.1.29.0 mask 255.255.255.0
network 150.1.2.0 mask 255.255.255.0
aggregate-address 136.1.0.0 255.255.0.0
aggregate-address 150.1.0.0 255.255.0.0 summary-only
neighbor 136.1.23.3 remote-as 100
neighbor 136.1.29.9 remote-as 100
neighbor 136.1.245.5 remote-as 200
neighbor 136.1.245.5 advertise-map ADVERTISE
non-exist-map TRACK_PPP
no auto-summary
R2#show ip route | incl Null
B 136.1.0.0/16 [200/0] via 0.0.0.0, 00:17:18,
