Hi Group,

I am doing a prefix-list filtering from a backbone router (BBR). The routes
send by BBR to router1 via eigrp is:

1.1.1.0/24
1.1.2.0/24
1.1.3.0/24
1.1.4.0/24
1.1.5.0/24
1.1.6.0/24

only 1.1.1.0, 1.1.4.0 and 1.1.5.0 are allowed to be received by router1.
below is what i have done on router 1:

ip prefix-list frombbr seq 5 permit 1.1.1.0/24
ip prefix-list frombbr seq 10 permit 1.1.4.0/24
ip prefix-list frombbr seq 15 permit 1.1.5.0/24

router eigrp 1
distribute-list prefix frombbr in

This works fine, but I am just wondering if there is a shorter way of doing
this, like do the task with only 1/2 prefix list. Or is there any simpler
way to accomplish the task?

Thanks and regards - SH
