Hello *,
can any one give me more details on
* how the LER / LSR failure handled.

ex:if we have a n/w as shown

           a2---------------a4--------
           |                          |
a1---------|                          |
           |                          |-----a5
           |                          |
           a3--------------a5---------|       

where a! is a router's.

Imagine that Using MPLS the LSP is set to take a path
a2-a4-a5. Now that the packet is at router a2, now the
router a4 fails then how is the packet forwarding
done.

Plz provide me the details.

Pradeep
