BIG-IP APM Edge Client connects in full-tunnel VPN mode with "Allow Local Subnet" enabled, the route metrics are increased. Upon VPN disconnection, the client fails to restore/revert the original route metric values.
Causes communication/connectivity errors for end users after they disconnect from VPN, as traffic may be misrouted due to elevated metrics.
Full-tunnel VPN mode AND "Allow Local Subnet" enabled
None
Full-tunnel VPN with "Allow Local Subnet" enabled. Verified route metrics across 1 VPN connect/disconnect cycle using `route print`: All managed routes restored to exact original metrics (?=0). The multicast 224.0.0.0/4 on IF 11 shows +1 drift — this is Windows OS behavior (OS re-creates this route independently; not managed by EdgeClient). It does not accumulate any more.
