Configuration Roadmap
The configuration roadmap is as follows:
Issue 01 (2012-01-06)
Figure 2-9, Host visits the IP network using the default gateway.
RouterA and RouterB constitute a VRRP group, which functions as the default gateway of
the hosts.
RouterA functions as the gateway. When RouterA fails, RouterB becomes the gateway.
After RouterA recovers, it preempts to be the master within 20 seconds.
User packets sent from Switch carry two tags.
Configure VRRP on the QinQ termination subinterface GE2/0/0.1 on RouterA and
RouterB.
NOTE
AR2200-S cannot function as SwitchA.
