Pure Layer 2 Topology Without Integrated Routing and Bridging
Qualified Learning
Figure 13 on page 107 illustrates the chassis connecting to the PIM-DR is the primary active
router and the other is the secondary active.

In this application, interfaces I1, I2, I3, I4, I5, I6, I7, I8, I9 and I10 are single-homed interfaces.
The multichassis links ae0.0 and ae0.1 belong to the same bridge domain in both the
chassis. Interfaces I10, I1,I7,I3,I5, ae0.0 and ae0.1 are in same bridge domain, bd1 in P-A.
Interfaces I9, I2,I8,I4,I6, ae0.0 and ae0.1 are in same bridge domain, bd1 in S-A.
This discussion assumes the following configuration:
• In Primary Active and S-A, qualified learning is ON in bd1.
• Interfaces I1,I2,I3, ae0.0 and I4 belong to vlan1, learning domain ld1.
• Interfaces I7,I8,I5, ae0.1 and I6 belong to vlan2, learning domain ld2.
• Interfaces I9 and I10 belong to vlan3, learning domain ld3.
For the IGMP speakers (hosts and routers) in the same learning domain ld1, P-A and S-A
linked should appear to be one switch.
For the IGMP speakers (hosts and routers) in the same learning domain ld2, P-A and S-A
linked should appear to be one switch.
