A route-table entry is required for a FEC with a pop operation to be advertised. For a FEC
with a swap operation, a route-table entry must exist and the user-configured next hop for the
swap operation must match one of the next hops in the route-table entry.
The next-hop, advertised-label, and swap-label parameters are optional. If a next-hop is
configured but no swap-label is specified, the swap occurs with label 3 (implicit null), then
the label is popped and the packet is forwarded to the next hop. If the next-hop and
swap-label parameters are configured, a regular swap occurs. If no parameters are
specified, a pop and forwarding is performed.
Default no fec-originate
Parameters ip-address/mask — specifies the IP prefix and mask length
Values
advertised label — specifies the label advertised to the upstream peer. If not
configured, the label that is advertised should be from the label pool. If the configured
static label is not available, the IP prefix is not advertised.
in-label — the LSR to swap the label. If configured, the LSR should swap the label with
the configured out-label. If not configured, the default action is pop if the next-hop
parameter is not defined.
Values 32 to 2047
out-label — the number of labels to send to the peer associated with this FEC
Values 16 to 1048575
interface-name — specifies the name of the interface that the label for the originated FEC
is swapped to. For an unnumbered interface, this parameter is mandatory because
there is no address for the next hop. For a numbered interface, it is optional.
next-hop ip-address — specifies the IP address of the next hop
Values a.b.c.d
pop — specifies to pop the label and transmit the packet
ipv4-address a.b.c.d (host bits must be 0)
ipv6-address x:x:x:x:x:x:x:x (eight 16-bit pieces)
x:x:x:x:x:x:d.d.d.d
x: [0 to FFFF]H
d: [0 to 255]D
ipv6-prefix-length - [0 to 128]
mask 0 to 32
