Hi sudeep, Well, we are talking of a static routing scenario here. When we alreadly know the LSR, where where is the need to use the label space info? (well pardon me since i have still not read the doc. completely!). Since the labels on the LSRs are unique, there is no question of messing up. Well, as far as the simple routing is concerned, unique label for every FEC should work fine. May be its required in some other cases i.e. Tunnel etc. Am not sure. The other reason could be not to run out of labels!! - Padmini > Hi Padmini, > We are also in the process of creating a MPLS test-bed in IITB.
