Prefix list

[shayan_2k@hotmail.com]

Hello All 

I m receiving routes on router 2 from router 1 ranging from 10.104.1.0/24 to 10.104.140.0/24

but i wana advertise only advertise routes from 10.104.111.0/24 to 10.104.136.0/24

i want to create prefix list so i can apply that on route-map and then redistribute my selected network range to router 3 

any help to create Prefix list please

You can do example ;

ip prefix-list R2_TO_R3 seq 5 permit 10.104.111.0/24

ip prefix-list R2_TO_R3 10 permit 10.104.136.0/24

route-map R2_TO_R3  permit 10
 match ip address prefix-list R2_TO_R3 

apply this to IGP

Hello,

according to my calculation, you need to summarize as below:

ip prefix-list ADVERTISE_RANGE_111_136 permit 10 192.168.111.0/24
ip prefix-list ADVERTISE_RANGE_111_136 permit 20 192.168.112.0/20
ip prefix-list ADVERTISE_RANGE_111_136 permit 30 192.168.128.0/21
ip prefix-list ADVERTISE_RANGE_111_136 permit 40 192.168.136.0/24
