URR Format

The URR ID format is as given below:

  • URR ID is 32 bit.

  • MSB (32nd) bit for static/predefined URRs is set to 1, and for dynamic URRs is set to 0.

  • First four LSB bits are set for interface type.

    • 1 for offline

    • 7 for online

  • Bit 4-31 is for URR ID number.

    For example: Dynamic first URR if ID is 1:

    0x00 00 01 01 Offline

    0x00 00 01 07 Online

    Static/Predefined first URR if ID is 1:

    0x80 00 01 01 Offline

    0x80 00 01 07 Online
