antrea-egress0 is a dummy interface and supposed to be down by design. The usage of antrea-egress0 is kind of implementation specific. We can add some docs to clarify it but it's not a bug.
@tnqn , antrea-egress0 is a dummy interface, however if the externalippool is not in node's subnet, traffic is stopped (expected) and antrea-egress0 remain in down state, however when externalippool is in same subnet as node's network, traffic is going out, however keeping the antrea-egress0 as down might confuse user as src ip will be of antrea-egres0 interface. Documentation could help to clarify these.
While using static Egress, when same ip is provided as node's ip, there is no ip assigned to egress dummy interface( antrea-egress0 ), it is expected since ip is already assigned to node's interface, hence can not be reassigned to egress dummy interface Another candidate for documentation
5: antrea-egress0: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default

Describe the bug
Egress interface shown as down even when ipRanges are in same subnet as Node subnet or otherwise ? Traffic is going out with actual interface
To Reproduce
configure extermalippool resource with following config
create egress resource under egress crd
Expected
Egress interface status should be up
Actual behavior
