Hi All,
My config as follows but the summary route is still installed in the RIB
despite configuring AD 255:
R1
-- ! interface FastEthernet0/0 ip address 150.50.17.1 255.255.255.0 ip summary-address eigrp 1 172.16.0.0 255.255.0.0 255 ! interface FastEthernet0/1 ip address 172.16.1.1 255.255.255.0 ! router eigrp 1 network 150.50.0.0 network 172.16.0.0 no auto-summary !R1#sh ip ro ei 172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks D 172.16.0.0/16 is a summary, 00:04:11, Null0
Can you provide specific commands how you filtered off the summary route using distribute-list? Are you doing something like this:
! router eigrp 1 network 150.50.0.0 network 172.16.0.0 distribute-list 1 in no auto-summary ! access-list 1 deny 172.16.0.0 0.0.255.255 access-list 1 permit any !
No, it doesn't work either.
Now, let's say I configure "auto-summary" under EIGRP process. We will have two summary routes in the RIB: 172.16.0.0/16 and 150.50.0.0/16. How do you discard them?
Thank you.
B.Rgds, Lim TS
