JUNOSe 11.0.1 Release Notes
14
Known Behavior
Configuring CAC and bulk-configured VCs on the same ATM interface was
supported in previous JUNOSe Software releases. As a result, If you are
upgrading to the current JUNOSe release from a lower-numbered release,
configurations that use CAC and bulk configuration on the same ATM interface
continue to work. However, we recommend that you disable CAC on these ATM
interfaces to ensure continued compatibility with future JUNOSe releases.
BGP
The E Series router does not include the link-local IPv6 address in the next-hop
field of an MP-BGP update message carrying IPv6 routing information over IPv4
transport. This behavior is compliant with RFC 2545 but might have
interoperability issues with other implementations that depend on a link-local
IPv6 address in the next-hop field on a directly connected external BGP
peering.
Work-around:
Enable EBGP multihop configuration on the remote
(non–Juniper Networks) peer.
The following message might be displayed under certain conditions:
bgpConnections (default,0.0.0.0): TCP error code xx (...) occurred while accepting
inbound TCP connection
The message is generated when an unconfigured peer attempts to establish a
TCP session with an E Series router and a valid route to the source address of
the peer is absent from the router’s routing table.
If a valid route exists in the routing table, the following message is displayed
when an unconfigured peer attempts to establish a TCP session with an E Series
router; X.X.X.X is the source address of the unconfigured peer:
NOTICE 08/29/2001 16:50:11 bgpConnections (default,X.X.X.X): Inbound
connection refused - no peer X.X.X.X configured in core
BGP/MPLS VPNs
In a scaled environment, we recommend that you increase the hold timers for
the following protocols to appropriate values, based on the level of complexity
of the network and scaling settings, so as to enable graceful restart to be
completed successfully. [Defect ID 184974]

IS-IS
LDP
OSPF

For a sample configuration scenario that illustrates how to configure hold timers
for successful graceful restart in a scaled environment, see
