Usage Guidelines
The cts sxp node-id command configures the node ID of a network device.
An SXP node ID is used to identify the individual devices within the network. The node ID is a four-octet
integer that can be configured by the user. If it is not configured by the user, SXP picks a node ID itself using
the highest IPv4 address in the default VRF domain, in the same manner that EIGRP generates its node ID.
The node ID has to be unique in the network that SXP connections traverse to enable SXP loop prevention.
The SXP loop detection mechanism drops the binding propagation packets based on finding its own node ID
in the peer sequence attribute. Changing a node ID in a loop detection running SXP network could break SXP
loop detection functionality and therefore needs to be handled carefully.
Wait until the SXP bindings that are propagated with the particular node ID in the path attribute are deleted,
before you change the node ID.
A syslog is generated when you change the node ID.
Note
Specifies the node ID of the device. Enter the node ID in hexadecimal
format.
Specifies the type of interface.
Specifies the SXP peer IPv4 address.
