Making the interface passive to the EIGRPV6 process when a potential EIGRPV6 neighbor is attached to the link can prevent these two routers from becoming neighbors. Note that as long as one of the two routers has a passive interface, the neighbor relationship is not established. For example, consider router R4 in the example network in this chapter, whose G0/0 interface is connected to a LAN with no other routers. Currently, R4's configuration contains a subcommand for the ipv6eigrp1 interface on its G0/0 interface. If this command is accidentally lost (or removed as an experiment), R4 will not advertise the routes for the connected subnet (subnet 33, or 2001:DB8:l:33::/64). Example 18-7 shows this specific example. To recreate this problem, the ipv6eigrp1 command is not issued on R4's G0/0 interface, where EIGRP is disabled, even though it is before collecting the output on R4 in Example 18-7. Example 18-7 shows that R1 does not have access to the subExample 18-7 Routing Network 33 or EIGRP Topology Data for Routes Lost on Subnet 33 on R1Rl# show ipv6 route 2001:DB8:1:33:: % Route not foundRl# show ipv6 eigrp topology | include 2001:DB8:1:33 Rl#380 Chapter 10 Implementing IPv4 EIGRPEIGRPV6 neighborsFrom one perspective, the EIGRP neighbor relationship is simple. When two EIGRPv6 routers are on the same data link, they discover each other through EIGRPv6Hello messages. These Hello messages list a number of parameters, and the neighbor checks the Hello to determine whether the routers should become neighbors.. If the parameters match, each router adds the other to its EIGRPv6 neighbor table, as listed in the show ipv6eigrp neighbors command. If the parameters do not match, the routers do not become neighbors and do not add each other to their neighbor tables or list each other in the output of the show ipv6eigrp neighbors command. On the flip side. troubleshooting EIGRP neighbor relationships means that you must remember many details. Neighbors will check the list of parameters that must match. Also, there are other issues that can prevent a router from becoming a neighbor. Fortunately, EIGRPv6 uses the same list as EIGRPv4, with one significant difference: EIGRPv6 does not require neighbors to be on the samesubnet.
