Hello,

I'm hoping someone can help me with aggregating routes and with route-maps etc? Basically I am trying to aggregate the 10.222.0.0/20 (as its currently redistributing smaller /21 to /29s etc) network when advertised to the 10.218.2.33 (12344) peer and keep all the other routes as they are.

Anyone any ideas where I've gone wrong?

Cheers,
Peter

Code:
ip prefix-list Agg-Routes seq 5 deny 10.222.0.0/21 ge 21 le 32
ip prefix-list Agg-Routes seq 10 permit 0.0.0.0/0 ge 0 le 32
router aggregate
aggregate-address 10.222.0.0 20 protocol bgp
exit
route-map Agg-Routes permit 5
match ip address prefix-list Agg-Routes
exit
router bgp 12343
bgp router-id 10.222.14.193
no bgp restart-delete-remnants
timers bgp 7 21
network 10.218.255.0 mask 255.255.255.0
neighbor 10.218.4.206 remote-as 12341
neighbor 10.218.2.33 remote-as 12344
neighbor 10.218.2.33 next-hop-self
neighbor 10.218.2.33 soft-reconfiguration inbound
neighbor 10.218.2.33 aspath-prepend 5
neighbor 10.218.2.33 route-map Agg-Routes out
redistribute direct
redistribute kernel
redistribute bgp
redistribute static
redistribute aggregate
exit

I worked out what the problem was with this. Use the following to create AGG routes -

Code:
router aggregate
    aggregate-address 10.222.0.0 20 protocol direct
    exit
