What's Changed

Learn about what changed in this release for MX Series routers.

Infrastructure

  • Option to disable path MTU discovery— Path MTU discovery is enabled by default. To disable it for IPv4 traffic, you can configure the no-path-mtu-discovery statement at the [edit system internet-options] hierarchy level. To reenable it, use the path-mtu-discovery statement.

    [See Path MTU Discovery.]

VPNs

  • Increase in revert-delay timer range— The revert-delay timer range is increased to 600 seconds from 20 seconds.

    [See min-rate.]

  • Configure min-rate for IPMSI traffic explicitly— In a source-based MoFRR scenario, you can set a min-rate threshold for IPMSI traffic explicitly by configuring ipmsi-min-rate under set routing-instances protocols mvpn hot-root-standby min-rate. If not configured, the existing min-rate will be applicable to both IPMSI and SPMSI traffic.
