Commit check failing with the error: Cannot parse routing-option max-interface-supported in Junos 11.1 and 11.2

  [KB20977] Show Article Properties


Summary:
This article describes the issue of the commit check failure with with the error: Cannot parse routing-option max-interface-supported in Junos 11.1 and 11.2. This typically occurs when a non-EX Junos device is upgraded to Junor 11.1 or 11.2, and also if only OSPF or PIM is configured without anything, under edit routing-options.


Symptoms:
Considering the following conditions:
  • If OSPF or PIM is configured and
  • If nothing is configured in the [edit routing-options] stanza
The following error is displayed when trying to commit the changes into the active configuration:
[edit]
root@junos-device# commit
error: Cannot parse routing-option max-interface-supported
error: configuration check-out failed
Cause:

Solution:
There are two workarounds for this issue:
  • Configure any dummy route under [edit routing-options static]:
  • set routing-options static route 127.1.1.0 reject

  • Alternatively configure the following hidden command:
  • set routing-options max-interface-supported 0
This problem is evident only in Junos 11.1 and 11.2, not in Junos 10.4 and 11.3.
