VRF Configuration Mode
The following example shows how to enter VRF configuration mode:
RP/0/RSP0/CPU0:router# configuration
RP/0/RSP0/CPU0:router(config)# router eigrp 100
RP/0/RSP0/CPU0:router(config-eigrp)# vrf customer1
RP/0/RSP0/CPU0:router(config-eigrp-vrf)#
IPv4 Address Family Configuration Mode
The following example shows how to enter IPv4 address family configuration mode:
RP/0/RSP0/CPU0:router# configuration
RP/0/RSP0/CPU0:router(config)# router eigrp 100
RP/0/RSP0/CPU0:router(config-eigrp)# address-family ipv4
RP/0/RSP0/CPU0:router(config-eigrp-af)#
IPv4 VRF Address Family Configuration Mode
The following example shows how to enter IPv4 VRF address family configuration mode:
RP/0/RSP0/CPU0:router# configuration
RP/0/RSP0/CPU0:router(config)# router eigrp 100
RP/0/RSP0/CPU0:router(config-eigrp)# vrf customer1
RP/0/RSP0/CPU0:router(config-eigrp-vrf)# address-family ipv4
RP/0/RSP0/CPU0:router(config-eigrp-vrf-af)#
Interface Configuration Mode
The following example shows how to enter interface configuration mode in IPv4 address family configuration
mode:
RP/0/RSP0/CPU0:router# configuration
RP/0/RSP0/CPU0:router(config)# router eigrp 100
RP/0/RSP0/CPU0:router(config-eigrp)# address-family ipv4
RP/0/RSP0/CPU0:router(config-eigrp-af)# interface GigabitEthernet 0/3/0/0
RP/0/RSP0/CPU0:router(config-eigrp-af-if)#
EIGRP Interfaces
EIGRP interfaces can be configured as either of the following types:
• Active—Advertises connected prefixes and forms adjacencies. This is the default type for interfaces.
• Passive—Advertises connected prefixes but does not form adjacencies. The passive command is used
to configure interfaces as passive. Passive interfaces should be used sparingly for important prefixes,
such as loopback addresses, that need to be injected into the EIGRP domain. If many connected prefixes
need to be advertised, then the redistribution of connected routes with the appropriate policy should be
used instead.
