RDKBDEV-3293 : Fix Condition check for adding default IPv6 route in WANManager

aprasad-97 · aprasad-97 · commit 4d471118cdc3 · 2025-11-16T23:30:12.000-08:00
Reason for change: After enabling Wan Manager Unification flag in MXL build, we observed that default IPv6 route for erouter0 was not getting added in CM during bootup. So fixed condition check to specifically check erouter0 interface while adding route.
Risks: Low
