OSPF redistribute into rip, does it has hop count limit

Dear all,

As I know, rip has maximum 15 hop counts.

If I redistribute ospf into rip, does rip router also will treat ospf redistributed route also has 15 maximum hop count.

Any document mention it ?

Hello Acbennyma,

yes OSPF routes redistributed into RIP will have a RIP metric with a maximum of 15.

Because OSPF metric is much wider (16 bi integer t for intra area route, 24 bit integer  for inter-area routes) it cannot be copied to RIP metric and you need to set a seed metric manually

example

router rip

redistribute ospf 100 route-map OSPF-INTO-RIP

default-metric 4

!

all OSPF routes redistributed into RIP will have RIP metric 4 in this example, the route-map can be used to filter what OSPF routes will be imported into RIP.

Hope to help
