JUNOS OS 10.4 Release Notes
82
In Junos OS Release 10.1 and later, you can use the router's main instance loopback
(
) address (rather than the multicast VPN loopback address) to establish the PIM
lo0.0
state for the multicast VPN. We strongly recommend that you perform the following
procedure when upgrading to Junos OS Release 10.1 if your draft-rosen multicast VPN
network includes both Juniper Network routers and other vendors' routers functioning
as provider edge (PE) routers. Doing so preserves multicast VPN connectivity throughout
the upgrade process.
Because Junos OS Release 10.1 supports using the router's main instance loopback (
address, it is no longer necessary for the multicast VPN loopback address to match the
main instance loopback adddress
NOTE: You might want to maintain a multicast VPN instance
to use for protocol peering (such as IBGP sessions), or as a stable router
identifier, or to support the PIM bootstrap server function within the VPN
instance.
Complete the following steps when upgrading routers in your draft-rosen multicast VPN
network to Junos OS Release 10.1 if you want to configure the routers's main instance
loopback address for draft-rosen multicast VPN:
Upgrade all M7i and M10i routers to Junos OS Release 10.1 before you configure the
1.
loopback address for draft-rosen Multicast VPN.
NOTE: Do not configure the new feature until all the M7i and M10i routers
in the network have been upgraded to Junos OS Release 10.1.
After you have upgraded all routers, configure each router's main instance loopback
2.
address as the source address for multicast interfaces. Include the
interface-name loopback-interface-name]
hierarchy level.
After you have configured the router's main loopback address on each PE router,
3.
delete the multicast VPN loopback address (
We also recommend that you remove the multicast VPN loopback address from all
PE routers from other vendors. In Junos OS releases prior to 10.1, to ensure
interoperability with other vendors' routers in a draft-rosen multicast VPN network,
you had to perform additional configuration. Remove that configuration from both
the Juniper Networks routers and the other vendors' routers. This configuration should
be on Juniper Networks routers and on the other vendors' routers where you configured
the lo0.mvpn address in each VRF instance as the same address as the main loopback
(lo0.0) address.
This configuration is not required when you upgrade to Junos OS Release 10.1 and use
the main loopback address as the source address for multicast interfaces.
