A.LDP synchronization can be deployed on the Loopback interface.

B.LDP establishes neighbors faster than ISIS, so LDP synchronization is turned off by default

C.LDP synchronization can be turned on globally.

D.LDP synchronization avoids traffic loss when the active-standby link is switched.

A.The device assigns a label to each route of the VPN-Instance vpna.

B.VPN-Instance vpna does not receive VPN routes with an RT of 2:1.

C.The GigabitEthernet 1/0/0 interface is tied to the VPN-Instance vpna

D.The total number of instances that enable the IPv6 address family in the VPN configured on this side is 1.

A.You can create multiple VRRP backup groups on one interface of a router . The router can act as a master for one VRRP backup group and as a backup for other VRRP backup groups

B.When configuring priority, make sure that the same router acts as a master in the three VRRP backup groups

C.When you deploy load sharing, hosts in the same LAN are required to configure the IP addresses of different virtual routers as gateway addresses for missing provinces

D.VRRP load sharing requires at least two virtual routers to provide forwarding services at the same time

A.IPv4, IPv6 using the same topology for SPF calculation

B.Does not have any meaning

C.SPF calculation is performed separately in the topology of IPv4 and IPv6,

D.SPF calculation for IPv6 is not supported

A.BGP4+? Router-ID ? BGP4 ? Router-ID-??

B.BGP4 configures the reflector, the role positioning of the reflector and the client needs to be consistent with the configuration of BGP4

C.The next hop of a BGP4 route can use the Link-Local address.

D.BGP4 specifies p

E.BGP4+ does not support route reflectors.
