Missing RIP Routes

[feroz syed]

Routes are visible on PE routers but on client side no rip routes showing. PE and Client connected with RIP protocol. Attached topology screenshot. Below show cmds and configs available.

Hello

You redistributing bgp intp rip without any metric, rip wont understand those bgp routes otherwise.
router rip
address-family ipv4 vrf RIP
redistribute bgp 65000 metric 5

Also you could just advertise a default route ino the ce rtr rib table
router rip
address-family ipv4 vrf RIP
default-information originate

it works !! but how could it happen because on R6 PE router we redistribute Rip route to Bgp , it affect on other side of the client or PE router. how this command "redistribute bgp 65000 metric 5" here we export the routes to BGP, but on PE which is R6 it already has Routes coming from R2-PE . if the redistribute cmd under bgp protocol means there is some logic, but here am totally confused. Thanks for your reply.

Hello

Route redistributed into bgp will be assigned with bgp attributes including weight and admin distance these ebgp routed are routed within the bgp vpn between the pe rtrs of R6-R2 however for those now bgp routes to be seen as valid rip routes in the vrf of the r1 then rip needs to understand these bgp routes in the form of a redistribution route with metric hence why you need to append a metric value that the rip protocol understands
