A. The establishment of the LSP FEC LSP LSR is to tie the actual and the demarcation label and bind the
notification to the upstream process.

B. By default, the same LSR FEC is targeted, and the received mapping can only be from the next hop
label, not from the next hop.

C. Label release in the DoD FEC LSR mode, in the specific pair, no need to obtain the message from the
upstream, the distribution and distribution of the label, please enter the label

D. When the topology of the network causes the next hop to change to the neighbor, use the free-hold label
to directly use the original non-next hop LSR.
Rapid reconstruction label LSP

A. IBGP ALoopback BGP establishes a stable neighbor relationship for the interface address.

B. PE-CE OSPF IS-iS EBGP exchange routing can be static routing, multiple instances, multiple examples,

C. BGP Soo VPN MPLS Soo MP-BGP is used to prevent routes routed from one site from going back to
the site through the backbone network. Self-generated Expansion group

D. The TTL field in the tag has a function to prevent the path.

A. The PIM-SM router with the smallest IP address is elected as the DR.

B. The PIM-SM router with the lowest DR priority is elected as the DR.

C. DR priorities of the PIM-SM routers are compared first. If their DR priorities are the same, their interface IP addresses are then compared.

D. The PIM-SM router with the longest interface mask is elected as the DR.
