I have a doubt regarding the route tag size used by different routing protocols. As per I know EIGRP, OSPF & BGP use 32 bit tags but the below document by cisco says RIP V2 uses a 16-bit tag:
Can somebody please clarify if the route tag size is same for all routing protocols or is it different?
Thanks a lot in advance
route tag size is not the same for all protocols as you noted.
RIPV2 and may be ISIS should have a 16 bit route tag field, other protocols have a 32 bit route tag field as you have noted
This has to be taken in account in multi protocols scenarios.
Hope to help
