Resiliency Enhancement for IPv4 and IPV6 Static Routes
- Initially verify devices and activate their static routes, without waiting for inbound user traffic, and without requiring configuration of device MAC addresses.
- Detect silent device outages and inactivate corresponding static routes.
- Reactivate static routes after device recovery, or hardware replacement with a new MAC address.
ExtremeXOS previously supported similar protection and resiliency using BFD on IPv4 static routes. However, BFD can only be used when the local and remote device both support BFD.
Supported Platforms
Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X620, X440-G2 series switches.
New CLI Commands
configure iproute add [default | ipv4_or_ipv6_network] gateway {protection [bfd | ping |none]}
configure iproute {ipv4 | ipv6} protection ping interval seconds miss misses
enable iproute {ipv4 | ipv6} protection ping
disable iproute {ipv4 | ipv6} protection ping
show iproute {ipv4 | ipv6} protection ping {v4_or_v6_gateway} {vr vr_name} {detail}
Changed CLI Commands
- The configuration settings for static route ping protection enable/disable, interval, and misses for IPv4 appear in the show ipconfig command, and for IPv6 in the show ipconfig ipv6 command.
- A new route flag letter "I" appears in the show iproute and show iproute ipv6 commands to indicate static routes with ICMP ping protection. Flag letter "I" uses the same column as flag letter "b" because BFD and ping protection are mutually exclusive. If the route flags also show "U" for Up, then ping protection detected the gateway is up.
