Enabled bridge mode on sercomm ont but unsure if it's working properly as bridge mode.

[gotoh_san]

I've connected another router(mercusys) to sercomm AOT 4221SR ont on airtel fibre via bridge mode. Internet seems to be working fine but I'm not really sure if it's bridged properly as wifi didn't get disabled on the ont and I've had to to it manually.
I connected the 3rd party router to lan 4 after enabling bridge on sercomm ont and logged in with pppoe credentials.
Is there any way to know that I've connected properly through bridge mode?
I've tried the traceroute command mentioned on web and it's returning only 1 private ip in gateway, so should i take it that there's no double nat issue and my connection is bridged, or am I missing something?

Brdr, bridge mode doesn't disable your ONT's WiFi.

I see. When searching for bridge mode on web, some search results were suggesting that it disables routers wifi, so I thought it must be so. Is there any other way to confirm that bridge mode is working?

Brdr, you are able to dial PPPoE, that itself is the biggest indication.
