The ip nhrp authentication ..., ip nhrp network-id ... and tunnel key ... commands are used to map the tunnel packets and the NHRP packets to the correct multipoint GRE tunnel interface and NHRP network when they are received on the hub.
To enable the Next Hop Resolution Protocol (NHRP) on an interface, use the ip nhrp network-id command in interface configuration mode. To disable NHRP on the interface, use the no form of this command.
ip nhrp network-id number
no ip nhrp network-id [number]
Globally unique, 32-bit network identifier from a nonbroadcast multiaccess (NBMA) network. The range is from 1 to 4294967295.
NHRP is disabled on the interface.
This command was introduced.
This command was integrated into Cisco IOS Release 12.2(33)SRA.
This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.
In general, all NHRP stations within one logical NBMA network must be configured with the same network identifier.
Notice the last part.
Kind of like BGP or EIGRP, if you create this you will need to make sure that all networks that connect together and need to talk will have the same network-id number.
We are pleased to announce availability of Beta software for 16.6.3.
16.6.3 will be the second rebuild on the 16.6 release train targeted
towards Catalyst 9500/9400/9300/3850/3650 switching platforms. We are
looking for early feedback from customers befor...
