The router RTA and RTB are eBGP neighbors. RTA advertises the route 10.10.10.0/24 and sets the community attribute, but checks the routing table of RTB and finds that the route 10.10.10.0/24 learned from RTA does not carry the community attribute. May I ask what may be the reason for the loss of group attributes?
