    Re-route PRI traffic via MPLS WAN link

    Could any one help me for the below BCP plan. We are several small remote sites connecting to Core Datacenter via WAN MPLS link. All sites local cisco phones are registered in the call manager in Core DC. All remote sites having seperare PRI lines for outbound calls. My question if the local PRI circuit went down, then is it possible to re-route the remote site PRI traffic via WAN MPLS. So the PRI down remote site PRI traffic should go via Core DC site PRI line. I'm not an expert in networking. Need your idea, re-route config (both source and destination end) for doing this BCP plan.

    BGP configuration crashed

    Hi , My BGP configuration got crashed out(lossed) after the cisco router(2911) IOS upgrade. After IOS upgrade I have reloaded the router and the network connection got lost. I have tried to login the router via serial connection(pc to console port), but its asking the enable password and my passwords are not worked. Later I have tried with the cisco password recovery options and logged in. Is both BGP config crash and enable password crashed are related one. Why this happened during the IOS upgrade. Any preventive measures there to avoid this issues in future? Please... Upgraded IOS version is c2900-universalk9-mz.SPA.151-4.M4.bin Thanks
