Chapter 39 Configuring IPv6 Host Functions and Unicast Routing
Understanding IPv6
Prefix Lists
Use the distribute-list prefix-list command to define which networks running EIGRP IPv6 are to
receive routing updates. The route-map command is not supported for route filtering with a distributed
list.
Router ID
An instance of EIGRP IPv6 requires that you have a router ID before it can run. As with IPv4, EIGRP
IPv6 supports implicit and explicit router IDs. An implicit router ID is derived from a local IPv4 address,
so any IPv4 node always has an available router ID. However, EIGRP IPv6 might be running in a network
with only IPv6 nodes and therefore might not have an available IPv4 router ID. You can use the show
ipv6 eigrp command to see whether a router ID has been configured, and you can use the router-id
command to set an explicit router ID.
Passive Interfaces
As with EIGRP IPv4, you can use EIGRP IPv6 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, and 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 39-2 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 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 can 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.
