Mlppp; Mpls; Multicast - Juniper JUNOSE SOFTWARE 11.0.1 - RELEASE NOTES 7-14-2010 Release Note

MLPPP

MPLS

Multicast

When you install an ES2-S1 Redundancy IOA with a hardware revision number
of -02 or less in slot 0 or slot 11 of the E320 router or in slot 0 or the E120
router, do not install an OCx/STMx ATM IOA or an OCx/STMx POS IOA in the
lower (E320) or left (E120) adapter bay of slot 1 or slot 12. When the spare line
module is controlling another slot and you revert back to the primary line
module, the ATM or POS IOAs can become unusable or cause the line module to
reset. [Defect ID 69760]
Work-around: This problem is not present for ES2-S1 Redundancy IOAs with a
hardware revision number of -03 or higher.
Do not configure both MLPPP fragmentation (with the ppp fragmentation
command) and IP fragmentation of L2TP packets (with the ip mtu command)
on the same interface. Instead, you must choose only one of the fragmentation
configurations by setting it to the necessary value and set the other
fragmentation configuration to the maximum allowable value.
Martini circuits configured on the ES2 10G LM act as true layer 2 tunnels,
without modifying the layer 2 headers. For this reason, Martini VLAN retagging
is not currently supported.
If you are upgrading to Release 7.1.0 or a higher-numbered release from a
release numbered lower than Release 7.1.0, and have inter-AS option B or C
configurations, you must explicitly configure MPLS on all inter-AS links, as in
the following example:
host1#configure terminal
host1(config)#interface fastEthernet 2/0
host1(config-if)#ip address ...
host1(config-if)#mpls
If you do not explicitly configure MPLS on the links, the inter-AS feature will not
work properly.
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. The configuration of the multicast group's OIF
membership from the SRP module to the line module exceeds the size of a
single message and is sent in fragments. Because of this fragmentation, the ES2
10G LM generates the following error message: [Defect ID 81768]
pc: 0x9e5c88: -> fatalPanic(void) offset: 0x8
