Incorrect routing information 
Symptom 
OSPFv3 cannot find routes to other areas. 
Analysis 
The backbone area must maintain connectivity to all other areas. If a router connects to more than one 
area, at least one area must be connected to the backbone. The backbone cannot be configured as a 
stub area. 
In a stub area, routers cannot receive external routes , and interfaces connected to the stub area must be 
associated with the stub area. 
Solution 
1.  Use the  display ospfv3 peer  command to...

Configuring IPv6 IS-IS 
This chapter describes how to configure IPv6 IS-IS, which supports all IPv4 IS-IS features except that it 
advertises IPv6 routing information instead. For information about IS-IS, see  Configuring IS-IS.  
T

he term router in this chapter refers to both routers and Layer 3 switches. 
Hardware compatibility 
The HP 5500 SI Switch Series does not support IPv6 IS-IS.

NOTE: 
The ipv6 filter-policy export  command is usually combined with the  ipv6 import-route command. If no 
protocol is specified for the  ipv6 filter-policy export  command, routes redistributed from all routing 
protocols are filtered before advertisement. If a protocol is specified, only routes redistributed from the 
routing protocol...

BFD for IPv6 IS-IS configuration example 
Network requirements 
As shown in Figure 114, c onfigure IPv6 IS-IS on Switch A, Switch B, and Switch C and configure BFD over 
the link Switch AL2 SwitchSwitch B.  
After the link between Switch B and the Layer-2 switch fails, BFD can quickly detect the failure and notify 
IPv6 IS-IS of the failure. Then Switch A and Switch B communicate through Switch C.
