Multicast Vpn Configuration Task List - HP A8800 Configuration Manual

Multi-hop EBGP interconnectivity
As shown in
autonomous system boundary router (ASBR) for AS 1 and AS 2 respectively. PE 3 and PE 4 are
interconnected through their respective public network instance and treat each other as a P device.
Figure 75 Multi-hop EBGP interconnectivity
In the multi-hop EBGP interconnectivity approach, only one MD needs to be established for all the ASs,
and public network multicast traffic between different ASs is transmitted within this MD.

Configuration prerequisites
CAUTION:
The MTU of the public network forwarding path must not be set below 1500; otherwise GRE multicast
packets will be fragmented on the public network, resulting in fragmented packets unrecognizable to the
destination PE device.
Before configuring MD-VPN, complete the following tasks:
Configure any unicast routing protocol on the public network.
