Hi, from customer router "CRA", I can't ping ISP router (126.96.36.199 route is not on CRA routing table). Then from service provider routes I can ping CRA just fine.
I did a trace from CRA to NAP (service provider router) and traffic dies on upstream, neighbor router GWA. I have some as-path and filter-list configured to control prefixes on CE and PE2 routers, but I still can't understand why I can't see 188.8.131.52 (servide provider network) on CRA.
Please find attached detailed diagram. Thanks.
