7.11.3.2 Communication with the local site
7.11.4 The peer of mp-BGP has not been established
Eliminate the fault in accordance with Subsection 7.6.3, “No BGP4 route information
exists”.
7.11.5 VC of EoMPLS(L2-VPN) has not been established
Execute the show mpls 12transport command to check the display of local VC label,
remote VC label, and tunnel label. The table below indicates the displayed contents
of the labels and the relevant check items.
3 Check to see if the adjacent router is
announcing the VPN route. If it is announcing, go to item 4.
If it is not announcing, check the adjacent router.
4 Check to see if -keep-none-vpn is
specified in the configuration definition
information. If specified, disconnect the relevant peer using the clear ip bgp
command temporarily, or have the VPN route announced once
again from the peer. If none of the above resolves the problem,
acquire the fault information through the relevant router.
dump protocols ipv4-unicast all*
If not specified, acquire the fault information through the relevant
router.
dump protocols ipv4-unicast all*

the local unit side.
Check the validity (VCID, L2transport Interface, Targeted peer) of
the configuration definition information of the local unit side.
2 When the remote VC label indication is
"-" Ensure that the 12transport circuit on the remote unit side is UP.
Check the validity (VCID, L2transport Interface, Targeted peer) of
the configuration definition information of the remote unit side.
