Multicast Vpn Configuration Task List - HP 6125XLG Ip Multicast Configuration Manual

Figure 64 VPN instance-VPN instance interconnectivity
By using this method, a separate MD must be established within each AS. VPN multicast data traffic
between different ASs is transmitted between the two MDs.
Because only VPN multicast data traffic is forwarded between ASBRs, different PIM modes can run within
different ASs. However, the same PIM mode must run on all interfaces that belong to the same VPN
(including interfaces with VPN bindings on ASBRs).
Multihop EBGP interconnectivity
As shown in
• A VPN network involves AS 1 and AS 2.
PE 3 and PE 4 are the ASBRs 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 65 Multihop EBGP interconnectivity
By using this method, only one MD needs to be established for all the ASs. Public network multicast traffic
between different ASs is transmitted within this MD.
