    Network Link Status

    umad

      Can someone answer it!


      Sometimes link is down but interfaces are not down .for example in the below topology R1 and R4 interfaces are up but if any problem Exist in the network between R2 and R3 I can not see in the map that I make in map maker . my links are up but i dont have access form R1 to R4 .

      i dont have Access to Routers Betweenn R2 and R3 (because these are leased one from ISP and the links type is Layer 2 VPN) . How can I monitor The link status between R2 and R3 ?
