RouterOS manual

NAME DYNAMIC-ID SELECT-D SELE

routing/id

Type: Directory

Global Router ID election configuration. The Router ID can be configured explicitly or elected from one of the router's IP addresses.

For each VRF table, RouterOS adds a dynamic ID instance that elects the Router ID from one of the IP addresses in that VRF:

[admin@rack1_b33_CCR1036] /routing/id> print
Flags: D - DYNAMIC, I - INACTIVE
Columns: NAME, DYNAMIC-ID, SELECT-DYNAMIC-ID, SELECT-FROM-VRF
#   NAME   DYNAMIC-ID      SELECT-D   SELE
0 D main   111.111.111.2   only-vrf   main

<ArgTableRow arg="X" typ="disabled">disabled</ArgTableRow> <ArgTableRow arg="D" typ="dynamic">dynamic</ArgTableRow> <ArgTableRow arg="I" typ="inactive">If there was a problem getting a valid ID, then the item can become inactive.</ArgTableRow>

<ArgTableRow arg="name" typ="string"></ArgTableRow> <ArgTableRow arg="id" typ="ipAddr" unset="1">Router ID to set explicitly. If the Router ID is not set, RouterOS can elect it from one of the configured IP addresses. See select-dynamic-id and select-from-vrf.</ArgTableRow>

Select which IP addresses RouterOS uses for Router ID election:

  • any - any address found on the router can be elected as the Router ID.
  • lowest - select the lowest IP address.
  • only-static - pick only statically configured addresses.
  • only-active - select an ID only from active IP addresses.
  • only-loopback - select an ID only from loopback addresses (loopback address is any non-point-to-point /32 address).
  • only-vrf - select an ID only from the selected VRF. Works with select-from-vrf.

<ArgTableRow arg="select-from-vrf" typ="enum" unset="1">VRF from which to select IP addresses for the ID election.</ArgTableRow>

<ArgTableRow arg="dynamic-id" typ="ipAddr">Currently selected ID.</ArgTableRow>
