direction of SOO tagging
I'm finding conflicting information about the SoO tagging process. Do the tags go from EIGRP to BGP for the use of mBGP or the other way around? I'm going to try to use deductive reasoning and see if I hear otherwise.
The SoO tagging is an extcommunity tag. The extcommunity tag is TLV infomation in the VPN route information. Therefor the SoO tagging is applied in the direction of redistribution of EIGRP INTO mBGP correct? Doesn't mBGP use the SoO tag as a loop prevention mechanism? There isn't any way for non-IPV4 EIGRP running through the back-door to use SoO extcommunity tags. Right?
