notice

Message format string

In network-instance network-instance, the number of family routes received from the neighbor peer-address has exceeded the configured limit.

Cause

The number of received routes from the peer has exceeded the configured limit for the associated address family.

Effect

Event name

bgpNeighborPrefixLimitThresholdReached

Default severity

notice

Message format string

In network-instance network-instance, the number of family routes received from the neighbor peer-address has exceeded the configured threshold, which is warning-threshold-pct% of the limit.

Cause

bgp

Event name

bgpOutgoingDynamicPeerLimitReached

Application name

bgp

Event name

bgpPathAttributeDiscarded

Default severity

warning

Message format string

In network-instance network-instance, a path attribute of type attribute-type and length attribute-length was discarded in a route received from the neighbor peer-address.

Cause

The path attribute was malformed and the attribute-discard approach is used for this type of attribute.

Effect

The intended meaning of that path attribute is not applied but the UPDATE message is still processed for new reachabiity information.

Application name

bgp

Event name

bgpPathAttributeMalformed

Default severity

warning

Message format string

In network-instance network-instance, a path attribute of type attribute-type and length attribute-length that was received in a route from the neighbor peer-address was considered malformed.

Cause

The router considers a path attribute to be malformed, for example not the expected length. The UPDATE message can still be parsed though.

Effect

Dependent on the type of the malformed path attribute. Either the malformed attribute is discarded or else the entire UPDATE message is considered to have unreachable NLRI.

Application name

bgp

Event name

bgpRouteWithdrawnDueToError

Default severity

warning

Message format string

In network-instance network-instance, a route for NLRI nlri was received from neighbor peer-address and it was considered withdrawn because of a recoverable error in the UPDATE message.

Cause

The router received a malformed UPDATE and the malformed path attribute(s) require as a treat-as-withdraw error handling behavior for the included set of routes.

Effect

There is no reachability for the NLRI in the malformed UPDATE message.

Application name

bgp

Event name

bgpUpdateInvalid

Default severity

warning

Message format string

In network-instance network-instance, an UPDATE message received from neighbor peer-address was considered invalid and caused the connection to be closed because the NLRI could not be parsed correctly.

Cause

The router received a malformed UPDATE which made it is impossible to identify all of the NLRI correctly.

Effect

The session is shutdown.
