Release Information

Statement introduced before JUNOS Release 7.4.

Statement introduced in JUNOS Release 9.0 for EX Series switches.

Description

Check whether the reserved fields in a RIP packet are zero:

  • check-zero—Discard version 1 packets that have nonzero values in the reserved fields and version 2 packets that have nonzero values in the fields that must be zero. This default behavior implements the RIP version 1 and version 2 specifications.
  • no-check-zero—Receive RIP version 1 packets with nonzero values in the reserved fields or RIP version 2 packets with nonzero values in the fields that must be zero. This is in spite of the fact that they are being sent in violation of the specifications in RFC 1058 and RFC 2453.

Default

check-zero
