3. Configure route filtering:
# Use IPv6 prefix lists on Switch B to filter received and redistributed routes.
[SwitchB] ipv6 prefix-list aaa permit 4:: 64
[SwitchB] ipv6 prefix-list bbb deny 2:: 64
[SwitchB] ipv6 prefix-list bbb permit :: 0 less-equal 128
[SwitchB] ripng 1
[SwitchB-ripng-1] filter-policy prefix-list aaa export
[SwitchB-ripng-1] filter-policy prefix-list bbb import
[SwitchB-ripng-1] quit
# Display RIPng routing tables on Switch B and Switch A.
[SwitchB] display ripng 1 route

RIPng route redistribution configuration example
Network requirements
As shown in Figure 94, Switch B communicates with Switch A through RIPng 100 and with Switch C
through RIPng 200.
Configure route redistribution on Switch B, so the two RIPng processes can redistribute routes from
each other.
