Unsupported IPv6 Host Functions and Unicast Routing Features
The Catalyst Switch Module 3110 does not support these IPv6 features:
• IPv6 policy-based routing
• IPv6 virtual private network (VPN) routing and forwarding (VRF) table support
• Support for these IPv6 routing protocols: Multiprotocol Border Gateway Protocol (BGP),
Intermediate System-to-Intermediate System (IS-IS) routing
• Simple Network Management Protocol (SNMP) over IPv6 transport
• IPv6 Hot Standby Router Protocol (HSRP)
• DHCPv6
• IPv6 packets destined to site-local addresses
• Tunneling protocols, such as IPv4-to-IPv6 or IPv6-to-IPv4
• The switch as a tunnel endpoint supporting IPv4-to-IPv6 or IPv6-to-IPv4 tunneling protocols
• IPv6 unicast reverse-path forwarding
• IPv6 general prefixes
The Catalyst Switch Module 3012 does not support these IPv6 host functions:
• IPv6 unicast routing
• IPv6 multicast routing
• IPv6 QoS
• Most IPv6 ACLs
show ipv6 eigrp topology [as-number | ipv6-address]
[active | all-links | detail-links | pending | summary |
zero-successors]
Displays EIGRP entries in the IPv6 topology table.
debug ipv6 eigrp [as-number] [neighbor ipv6-address
| notification | summary]
Displays information about EIGRP IPv6.
debug eigrp fsm Displays debugging information about EIGRP feasible successor
metrics (FSMs).
debug eigrp neighbors Displays neighbors discovered by EIGRP.
debug eigrp packet Displays debugging information for EIGRP IPv6 packets.
debug eigrp transmit Displays messages sent by EIGRP.
debug eigrp nsf Displays NSF notifications and information about NSF events in an
EIGRP network.
clear ipv6 eigrp [as-number] [neighbor ipv6-address] Deletes entries from EIGRP IPv6 routing tables.
