I have a remote router (R1) with 2 neighbors routers (R2 & R3) using EIGRP. EIGRP chooses R2 as its default route.
My questions is, what would be the effect in the default route if i used the "distribute-list" command in R1 due to a bouncing link between R1 and R2?
Ex. R1(config)# access?list 20 deny any
R1(config)# router eigrp 1
R1(config?router)# no passive?interface serial 0
R1(config?router)# distribute?list 20 out serial 0
I know that when the distribute-list command is configured on an interface, all outgoing routing updates only will be blocked and all incoming routing updates will be allowed, making R2 continuously send routing updates to R1.
R1 and R2 would still establish EIGRP adjacency. However, your distribute list would prevent routing updates from being sent out serial 0 on R1 but it would still accept routes learned from neighbor(s) connected via serial 0. Distribute list is direction based (in or out). Hence, 'distribute list out' would in no way affect the routes that are learned from the neighbors.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
