JunosE 11.3.0 Release Notes
Multicast
30
Known Behavior
The ip dipe sg-cache-miss and ipv6 dipe commands are not intended or supported
for customer use, although they are visible in the User Exec and Privileged Exec
modes respectively. These commands are intended to be used in a Juniper Networks
internal lab environment for testing without a traffic generator.
Do not configure a multicast group with more than 10,219 outgoing interfaces (OIFS)
on the same ES2 10G LM. [Defect ID 81768]
When you upgrade a router running a release earlier than JunosE Release 8.2.x to
JunosE Release 8.2.x or higher-numbered releases, the Protocol Independent
Multicast (PIM) configuration settings in VPN routing and forwarding (VRF)
instances are not restored after the upgrade is completed. This problem happens
only if you did not previously configure PIM on the parent virtual router (VR) for the
VRF. This problem occurs with both IPv4 PIM and IPv6 PIM configurations on the
router.
After the completion of the upgrade process, if you attempt to restore the PIM
configuration directly on the VRF, an error message is displayed. For example, if you
try to restore the IPv4 PIM settings on the VRF using the router pim command, the
following error message is displayed:
host1:vrf01(config)#router pim
% PimIp not configured on this router
Work-around: To correct this problem after you upgrade a router running a release
earlier than JunosE Release 8.2.x to JunosE Release 8.2.x or higher-numbered
releases, you need to restore the PIM configuration on the upgraded router in two
steps (first, on the parent VR, and then, on the VRF), instead of attempting to restore
the PIM configuration directly on the VRF.
To restore IPv4 PIM configuration on the VRF, perform the following steps. These
steps assume that a parent VR context, named "parent", and a VRF in the parent VR,
named "vrf01", are already configured on the router.
1.
Access the context of the parent VR, and create and enable IPv4 PIM on the
parent VR.
host1(config)#virtual-router parent
host1:parent(config)#router pim
2.
Enter the VRF Configuration mode to restore PIM settings on the VRF in the
parent VR.
host1:parent(config)#virtual-router parent:vrf01
3.
Create and enable IPv4 PIM on the VRF in the parent VR.
host1:parent:vrf01(config)#router pim
After the IPv4 PIM configuration is recovered on the VRF, you can remove the IPv4
PIM configuration settings on the parent VR by using the no router pim command,
if necessary.
To restore IPv6 PIM configuration on the VRF, perform the following steps. These
steps assume that a parent VR context, named "parent", and a VRF in the parent
VR, named "vrf01", are already configured on the router.
