…to bad type match The ecommunity_non_transitive() helper incorrectly used CHECK_FLAG() to test against ECOMMUNITY_ENCODE_IP_NON_TRANS (0x41), which is a full type code, not a bitmask. As a result, type 0x03 (transitive opaque), used for encapsulation (e.g., VXLAN), was mistakenly matched and stripped during re-announcement. This patch replaces the incorrect CHECK_FLAG() with a direct equality check. Bug caused stripping of valid VXLAN encapsulation communities (type 0x03) on reflected UPDATEs.
