What is the significance of the 1 in the following configuration?
router(config)# router eigrp 1
A.
It is the process ID for EIGRP and is locally significant to this router.
B.
It is the process ID for EIGRP and must be the same on all EIGRP routers.
C.
It is the AS number for EIGRP and is locally significant to this router.
D.
It is the AS number for EIGRP and must be the same on all EIGRP routers.
Explanation:
Enhanced Interior Gateway Routing Protocol (EIGRP) configuration requires the specification of an
Autonomous System (AS) number with the router eigrp command. Any number can be chosen, but it must
match on all EIGRP routers in the domain. This value may appear to be is similar to one used in enabling
OSPF, which demands a process ID number but that value is locally significant to each router and need not
match on each router.
The syntax of this command is router eigrp [autonomous-system]. Therefore, the 1 in the example indicates an
Autonomous System (AS) number, not a process ID.
The Autonomous System (AS) number is not locally significant to each router, and must match on all EIGRP
routers.
