IEIF expands the functions of OSPF by taking advantage of the strong expansibility of OSPF. To enable it to support IPv6 networks, the expanded protocol is called OSPFv3. OSPFv3 is compatible with OSPFv2.
MPLS can carry multiple network protocol services, including unicast IPv4 services, multicast IPv4 services, unicast IPv6 services, and multicast IPv6 services.
The figure shows the Router-LSA generated by a router. Which of the following statements are true based on the LSA?
In intra-domain MPLS VPN networks, data packets will be encapsulated with two layers of MPLS when they enter the public network and are forwarded.
label, the description of the two-layer label in the following options is wrong
Engineer Guan used two routers to test IPv6 services. By running the BGP4+ module to communicate with the branch, as shown in Juxin, an engineer captured packets to view the Updte packets sent by R1. Which of the following statements is true about the description of the message information?
Which of the following is the least likely cause of a VRRP backup group dual-active failure?
Which of the following commands can be used to view information about BGP VPNv4 routes and BGP private network routes on PEs
