System configuration commands
|
|
-----------------------------
|
|
|
|
.. cfgcmd:: set system ip disable-forwarding
|
|
|
|
Use this command to disable IPv4 forwarding on all interfaces.
|
|
|
|
.. cfgcmd:: set system ip disable-directed-broadcast
|
|
|
|
Use this command to disable IPv4 directed broadcast forwarding on all
|
|
interfaces.
|
|
|
|
If set, IPv4 directed broadcast forwarding will be completely disabled
|
|
regardless of whether per-interface directed broadcast forwarding is
|
|
enabled or not.
|
|
|
|
.. cfgcmd:: set system ip arp table-size <number>
|
|
|
|
Use this command to define the maximum number of entries to keep in
|
|
the ARP cache (1024, 2048, 4096, 8192, 16384, 32768).
|
|
|
|
.. cfgcmd:: set system ip multipath layer4-hashing
|
|
|
|
Use this command to use Layer 4 information for IPv4 ECMP hashing.
|
|
|
|
Zebra/Kernel route filtering
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
Zebra supports prefix-lists and Route Maps to match routes received from
|
|
other FRR components. The permit/deny facilities provided by these commands
|
|
can be used to filter which routes zebra will install in the kernel.
|
|
|
|
.. cfgcmd:: set system ip protocol <protocol> route-map <route-map>
|
|
|
|
Apply a route-map filter to routes for the specified protocol. The following
|
|
protocols can be used: any, babel, bgp, connected, eigrp, isis, kernel,
|
|
ospf, rip, static, table
|
|
|
|
.. note:: If you choose any as the option that will cause all protocols that
|
|
are sending routes to zebra.
|
|
|
|
Nexthop Tracking
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
Nexthop tracking resolve nexthops via the default route by default. This is enabled
|
|
by default for a traditional profile of FRR which we use. It and can be disabled if
|
|
you do not want to e.g. allow BGP to peer across the default route.
|
|
|
|
.. cfgcmd:: set system ip nht no-resolve-via-default
|
|
|
|
Do not allow IPv4 nexthop tracking to resolve via the default route. This
|
|
parameter is configured per-VRF, so the command is also available in the VRF
|
|
subnode.
|
