I have a PE router(PE1) in OSPF area 8 which is directly connected to another P (P1) router also in area 8 and this router connected to a P (P2) router which is area 0. Mpls with ldp is configured between all of them. OSPF is the IGP.
Every thing was working fine and suddenly I am not able to reach any of the IP in PE1 from area 0 and vice verca. I can see the route from both side. If I remove mpls configuration from PE1 then ping will be back.
I couldnt figure out what is going on. Can any one please help.
please let me know if there is any confusion in the scenareo
Thanks for your reply guys. We find the issue after working for the whole day. It has nothing to do with mpls. There is a wireless(Air Fibre) between PE and P routers which was mis behaving. After we restart the wireless device every thing back to normal. And still we dont have any idea how the wireless can behave like this. It was even blocking DNS, HTTP and Telnet.
