A.See the following entry in the BGP routing table: * 172.16.1.11/32 0.0.0.0 10 0? Indicates that the route is available non-optimal.

B.In the case where Pref-Val and local_preference are equal, if the BGP preference of the locally generated route, the IBGP route, and the EBGP route are the same, the locally generated valid route takes precedence.

A.If there are devices from other manufacturers on the network that do not support the LSP fragmentation function, the fragment extension mode must be configured to Mode-1, otherwise the devices of other manufacturers cannot recognize the packet.

B.When the amount of information in the link state protocol data message PDU to be released by ISIS is too large, the ISIS router will generate multiple LSP fragments to carry more ISIS information.

C.ISIS can choose whether to perform authentication verification on the received SNP and LSP packets.

D.After the router's LSP fragment extension function is enabled, you can use this function without restarting the ISIS process.
