Redistribution using tags
Tags provide an alternative method for redistributing routes. For instance, you can set tags when redistributing
routes into a domain and then use those tags for matches when redistributing those routes out of the domain. In
the following example, tags are set as the routes pass through the North router from the northern RIP domain to
the OSPF domain, and those tags are used for matching when the routes pass out of the OSPF domain through
the South router to the southern RIP domain.
Establish prefix lists on the North router to separate the "odd" and "even" routes:
ip prefix-list "Odds" seq 5 permit 10.1.11.1 255.255.255.0 ge 24 le 24
ip prefix-list "Odds" seq 10 permit 10.1.13.1 255.255.255.0 ge 24 le 24
ip prefix-list "Evens" seq 5 permit 10.1.12.1 255.255.255.0 ge 24 le 24
ip prefix-list "Evens" seq 10 permit 10.1.14.1 255.255.255.0 ge 24 le 24
Then set up a route map with separate sequences to tag the odd and even routes:
route-map "TagIn" permit seq 10
match ip address prefix-list "Odds"
set tag 1
exit
route-map "TagIn" permit seq 20
match ip address prefix-list "Evens"
set tag 2
exit
Set up a separate route map to match the connected routes, and assign the same tag value you used for the odd
routes. This allows you to propagate both the odd and the connected routes, but not the even routes, to the
southern RIP domain.
route-map "TagConn" permit seq 10
match source-protocol connected
set tag 1
exit
Redistribute the routes to the OSPF domain using the route maps:
