cisco nxos route redistribution

2011.11.06

wanted to redistribute some static routes into eigrp, this is handled differently in nxos.  all redistributes need to use a route map, easiest to populate the route map with a prefix list.

examine your static routes…

n7k1# sh run | inc "ip route "

ip route 0.0.0.0/0 10.0.0.2
ip route 10.10.10.0/24 10.0.0.4
ip route 10.20.10.0/20 10.0.0.1
ip route 192.168.172.0/24 10.10.10.3

create a prefix list of subnets you want into eigrp..

ip prefix-list examplestatic seq 15 permit 10.10.10.0/24
ip prefix-list examplestatic seq 20 permit 10.20.10.0/20
ip prefix-list examplestatic seq 25 permit 192.168.172.0/24

create a route-map, add your prefix-list to it…

route-map examplestaticmap permit 10
match ip address prefix-list examplestatic

add them to your eigrp instance…

router eigrp 14
 redistribute static route-map examplestaticmap

validate whether the routes showed up on your other routers; this is a downstream ios device:

2911#sh ip route 10.20.10.0

                       [170/52224] via 192.168.97.19, 3w5d, GigabitEthernet0/0

that’s it.  my examples show up twice because i did the redistribution on two n7ks.
