VOSS Reserved VLAN ID's and I-SIDs

VOSS Reserved VLAN ID's and I-SIDs

Anonymous

Hi,

Just compiling a list of possible VLAN ID and I-SID reservations to be aware of.

Reserved VLAN ID’s

If enable both vrf-scale flag and the spbmconfigmode flag, the switch reduces the number of configurable VLANs.

By default, VLAN IDs 1 to 4059 are configurable and the system reserves VLAN IDs 4060 to 4094 for internal use. 

On switches that support the vrf-scaling and spbm-config-mode boot configuration flags, if you enable these flags, the system also reserves VLAN IDs 3500 to 3998.

4051 - 4052 Typically allocated to B-VLANs

4048 - Onboarding VLAN

Reserved I-SID’s

24-bit I-SID can take vales between 1 and 16777215

16777001 is used and membership of the Fabric Area Network is announced in TLV 147

Multicast stream is allocated a dedicated I-SID from 16,000,001 to16,600,000

Is there anymore that I am missing?

Many thanks,

Martin

Just thought I would see if there is an update to the reservations, I ask, as seen the use of VLAN 4047 in relation to SD-WAN. So wondered if there was any others.

Many thanks.
