All,
 
Generally on the ingress edge hop ( for vpn cases ) 2 labels get pushed, upper tunnel/lsp label and the bottom VC label. The TTL for the upper label should be adequate enough for the hop-count of tunnel/lsp. What should be the TTL value of bottom label..
 
One possibility is to set it to a value same as the top label..Other possibility is to set it to "1" which ensures that VC does'nt travel more than one hop after it is exposed..
 
I would really appreciate if someone could point out what is recommended value if there is one... Thanks
 
with regards,
homp
