[mpls-linux-general] command help

[<kis...@wi...>]

Hi,
         In command "ip route add 10.200.19.1/32 via 10.200.19.1 spec_nh =
0x8847 0x2" what do we mean spec_nh=20

When I give command "mpls nhlfe show? i get the following:
 NHLFE entry key 0x00000002 mtu 1496 propagate_ttl
   push gen 11111 set eth0 ipv4 10.200.19.1 (0 bytes, 0 pkts, 0 dropped)
What do mean mtu 1496 propagate_ttl=20

The "ip rote show "gives the following:
   10.200.19.1 via 10.200.19.1 dev eth0 spec_nh 0x8847 0x2
   192.168.2.9/24 dev eth0 scope link
10.200.19.1/24 dev eth0 proto kernel scope link src 10.200.19,.1=20
127.0.0.0/8 dev lo scope link
what do mean scope link?

Also what are the commands to create table? and access the table?
Sorry for disturbing by these questions. As Iam new to these please help =
me.

Regards,
Kishor=20
