A. If using IS-IS as the PE-CE routing protocol, no redistribution is required.

B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required.

C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.

D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution.

E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.

t？As a Network Engineer, it is necessary for you to know how to implement MPLS VPNs between Customer Edge and Provider Edge routers.Refer to the following descriptions, which one is making sense？（）

A. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution

B. If using IS-IS as the PE-CE routing protocol, no redistribution is required

C. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required

D. If PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required

A.If RIPv2 is the routing protocol, only the path AD will be installed in the routing table by default.

B.If RIPv2 is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.

C.If EIGRP is the routing protocol, only the path AD will be installed in the routing table by default.

D.If EIGRP is the routing protocol, the equal cost paths ABD and ACD will be installed in the routing table by default.

E.If EIGRP and OSPF are both running on the network, the EIGRP paths will be installed in the routing table.

F.If EIGRP and OSPF are both running on the network, the OSPF paths will be installed in the routing table.

A. On the CE router, PE neighbors must be configured in the VRF context on the CE router

B. On PE routers, the CE IBGP neighbors are configured in the global BGP configuration

C. On PE routers, the CE EBGP neighbors are configured in the VRF context

D. A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router‘s other provider neighbors

A. It is a route to be used when the routing protocol fails.

B. It is a route configured by an ISP that sends traffic into a corporate network.

C. It is a route used when a packet is destined for a remote network that is not listed in the routing table.

D. It is a route manually configured for a specific remote network for which a routing protocol is not configured.

E. It is used to send traffic to a stub network.
