Introduction
IPv6 Etherchannel is not yet supported on Cisco IOS. Through this document we configure Layer 3 etherchannel between two switches, the two end points acts as GRE tunnel source and destination. IPv6 traffic is sent over GRE tunnel and hence using the bandwidth of Etherchannel.
Prerequisite
- Understanding and Configuring Layer 3 Etherchannel
- IPv6 Routing Protocols
Summary
Router R1 and Switch SW1 are forming OSPFv3 peering. Router R1 is advertising its loopback prefixes to SW1 through IPv6 OSPF routing protocol. Further SW1 and SW2 partipate in IPv6 RIP routing protocol over the GRE tunnel. The tunnel end points are the IPv4 interface of the Port-Channel (PO13). On SW1, IPv6 mutual redistribution is performed between OSPFv3 and RIPng.
The idea is to pass IPv6 traffic through Layer 3 Etherchannel.
