B. IS - IS is only capable of supporting IPv4 and CLNS.
C. IS - IS routers use ES - IS hellos (ESH) to establish and to maintain neighbor relationships.
D. IS - IS routers run the Bellman - Ford algorithm against their LSDBs to pick the best paths.
E. Level 1 routers learn about paths within the area of which they are a part.

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2? （）
A. Add the area 1 stub command on routers R1.
B. Add the always keyword to the default - information originate configuration command on router R2.
C. Remov e the default information originate configuration command from router R2 and place it on router R1.
D. Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.
A. The BGP split - horizon rule specifies that routes learned via EBGP are never propagated to other IBGP peers.
B. The BGP split horizon rule specifies that routes learned via IBGP are never propagated to other IBGP peers.
C. A full - mesh IBGP requires that neighbor relationships be established between a ll BGP enabled routers in the autonomous system.
D. IBGP neighbors must be in different autonomous systems.
E. An EGP or static routing is required between IBGP neighbors.
Refer to the exhibit and the partial configuration on router R2. On router R4 all RIP routes are redistributed into the OSPF domain. A second redistribu tion is configured on router R2 using a route map. Based on the configuration on router R2, which EIGRP external routes will be present in the routing table of R1?（）
A. the routes originating from the RIP routing domain
B. the routes originating from the OSPF stub area
C. all OSPF inter and intra - area routes
D. all routes originating from RIP and OSPF routing domains
Refer to the exhibit. Will redistribute d RIP routes from OSPF Area 2 be allowed in Area 1? （）
A. RIP routes will be allowed in Area 1 only if they are first redistributed into EIGRP.
B. Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1.
C. Redistrib uted RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1.
D. Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1.
E. Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
