[PR/466990]
On some M, MX, and T Series routers, when a family CCC filter is applied on
multiple interfaces that belong to different L2VPN routing instances, packet loss
may occur after the routing instances are deactivated and activated. As a
workaround, deactivate and activate the CCC filter on the interfaces. [PR/521357]
When you configure damping globally and use the import policy to prevent
damping for specific routes, and a new route is received from a peer with the
local interface address as the next hop, the route is added to the routing table
with default damping parameters, even though the import policy has a non-default
setting. As a result, damping settings do not change appropriately when the route
attributes change. [PR/51975]
When you issue the show ldp traffic-statistics
log message might be generated for all forwarding equivalence classes (FECs)
with an ingress counter set to zero: "send rnhstats GET: error: ENOENT
not found." [PR/67647]
If ICMP tunneling is enabled on the router and you configure a new logical system
that does not have ICMP tunneling enabled, the feature is globally disabled.
