A. N+1 backup

B. VRRP dual-machine hot standby

C. Dual-link hot backup

D. Dual-link cold backup

A. The ABR in the NSSA area will convert Type 7 LSA into Type 5 LSA, and inject the LSA into the backbone area, thereby flooding the entire OSPF domain

B. Type 3 LSAs are not allowed inside the NSSA area, nor are Type 4 and Type 5 LSAs allowed inside the area.

C. The ABR in the NSSA area will automatically inject a default route into the area, which is described by type 7 LSA

B. TRUE

A. When there are multiple effective routes in BGP, BGP Speaker only advertises the optimal route to the peer

B. BGP compares the originality of routes strictly according to the sequence when selecting routes. If the optimal route can be selected through the previous attributes, the latter comparison cannot be judged.

C. When BGP receives multiple routes to the same destination, it will select the optimal route according to the routing rules, and then deliver the optimal route to the IP routing table to guide data traffic forwarding

D. When BGP selects a route, if it cannot be optimized according to the conditions, it will automatically carry out load sharing
