Configures

The IP address to use as the source of NHRP reply packets

Default

The IP address of the interface that received the NHRP request

Description

This command specifies the interface whose IP address is used as the source for NHRP reply packets. Normally, the IP address of the interface that received the NHRP packet is used. This command is useful on next-hop servers because it allows a form of loop detection: the server can look for its own unique IP address.
