Switch Clustering Topologies And Interoperability With Other Products - Avaya 8800 Planning And Engineering

Redundant network design
For a given SMLT VLAN RSMLT is supported for any of the following scenarios:
• IPv4 Only: IPv4 is configured on the VLAN and IPv6 is not. RSMLT operation and logic
remains unchanged from the current implementation.
• IPv6 Only: IPv6 is configured on the VLAN and IPv4 is not. IPv6 RSMLT operation follows
that of IPv4 as described in this document.
• IPv4 and IPv6: Both IPv4 and IPv6 are configured on the VLAN. IPv4 RSMLT operation
and logic remains unchanged from the current implementation and unaffected by IPv6.
IPv6 operation follows that of IPv4 as described in this document.
Switch clustering topologies and interoperability with other
products
When the Avaya Ethernet Routing Switch 8800/8600 is used with other Avaya Ethernet
Routing Switch products, the switch clustering bridging, unicast routing, and multicast routing
configurations vary with switch type. Avaya recommends that you use the supported topologies
and features when you perform inter-product switch clustering. For more information, see

ERS 8800 / 8600 / 5500 / 8300 / 1600, NN48500-555.
