Configuring Multicast Hub and Spoke Topology: Example
route-policy A2-Hub-Policy
if extcommunity rt matches-any (4000:1, 4000:2, 4000:3, 4000:4) then
set rpf-topology vrf A2-Hub-Tunnel
elseif extcommunity rt matches-any (4001:1, 4001:2, 4001:3, 4001:4) then
set rpf-topology vrf A2-Spoke-Tunnel
else
pass
endif
end-policy
!
Any CE-PE protocol can be used. In this example, A2-Hub-3out exports all the hub and spoke routes to CE2
through EIGRP.
A2-Hub-3in uses route policy A2-Spoke-family to re-import selected spoke routes into PE2 through BGP.
