Chapter 39 Configuring IPv6 Unicast Routing
Understanding IPv6
Passive Interfaces
As with EIGRP IPv4, EIGRP IPv6 allows you to specify your EIGRP IPv4 interfaces and to select a
subset of those to be passive interfaces. Use the passive-interface default command to make all
interfaces passive, then use the no passive-interface command on selected interfaces to make them
active. EIGRP IPv6 does not need to be configured on a passive interface.
EIGRP IPv6 Commands
Table 39-1 shows the supported interface commands for EIGRP IPv6 on the switch.
For more complete syntax and usage information on these commands, see the Cisco IOS command
references.
Table 39-2 shows the supported router configuration commands for EIGRP IPv6 on the switch.
Table 39-1 EIGRP IPv6 Interface Commands for EIGRP IPv6
Command Purpose
ipv6 eigrp as-number Enables EIGRP IPv6 on a specified interface.
ipv6 authentication key-chain eigrp 1 name Enables authentication of EIGRP IPv6 packets.
ipv6 authentication mode eigrp as-number md5 Specifies the type of authentication used in EIGRP IPv6 packets.
ipv6 bandwidth-percent eigrp as-number percent Configures the percentage of bandwidth that may be used by EIGRP
IPv6 on an interface.
ipv6 hello-interval eigrp as-number seconds Configures the hello interval for the EIGRP IPv6 routing process
designated by an autonomous system number.
ipv6 hold-time eigrp as-number seconds Configures the hold time for a particular EIGRP IPv6 routing process
designated by the autonomous system number.
ipv6 next-hop-self eigrp as-number Informs the EIGRP IPv6 router that the IPv6 next hop is itself.
ipv6 split-horizon eigrp as-number Enables EIGRP IPv6 split horizon.
ipv6 summary-address eigrp as-number ipv6-prefix
[admin-distance]
Configures a summary aggregate address for a specified interface.
Table 39-2 EIGRP IPv6 Router-mode Commands
Command Purpose
ipv6 router eigrp as-number Specifies the EIGRP IPv6 routing process to be configured.
default-metric bandwidth delay reliability loading mtu Sets metrics for EIGRP IPv6.
distance internal-distance external-distance Allows the use of the best route to a node—either the internal or
external distance.
distribute-list prefix-list list-name Applies a prefix list to EIGRP IPv6 routing updates that are received
or sent on an interface.
log-neighbor-changes Enables the logging of changes in EIGRP IPv6 neighbor
adjacencies.
log-neighbor-warnings seconds Enables the logging of EIGRP neighbor warning messages.
maximum-paths number-paths Controls the maximum number of equal-cost routes that is
supported by a routing process for EIGRP IPv6.
