Hi Mohamed,
I really understand that, but the doubt is the following,
172.16.0.0------RA-------------RB-------------RC-------------RD
Config RB
router bgp 1
netw 172.16.0.0
neighbor x.x.x.x remote-as 2
RBsi
Tx the prefix if it has a route of 172.16.0.0 in the routing table. RB Rx
the route from RA by ospf, So RB tx the prefix with the IGP metric to RC
without THE ROUTE-MAP with set metric-type internal.
Question: How can I use a route-map with set metric-type internal?
Thanks,
Sergio
