Chapter 39 Configuring IPv6 Unicast Routing
Configuring IPv6
•
Stack member (must be running the IP services feature set):
–
receives CEFv6 routing tables from the stack master
–
programs the routes into hardware
Note
IPv6 packets are routed in hardware across the stack if the packet does not have exceptions
(IPv6Options) and the switches in the stack have not run out of hardware resources.
–
flushes the CEFv6 tables on master re-election
With IPv4 unicast routing, if the stack detects that the stack master is down and elects one of the stack
members the new stack master, except for a momentary interruption, the hardware continues to forward
packets with no active protocols. With IPv6, the switch does not continue forwarding packets. On
election of a new stack master, the stack might need up to 60 seconds to recover all routes and resume
forwarding traffic.
IPv6 host functionality is supported on the stack master, and all IPv6 applications run on the stack
master.
