Hi there,
I can help you with access to this router. Can I ask which vendor router is it?
A little about myself, I have over 11 years experience as network and security engineer. I have extensive experience with routing, switching, firewalls, load-balancers, design, and implementation of networks. I hold a Cisco CCIE Service Provider since 2015 and I am also a Juniper JNCIS-SP.
I have worked with ISPs and have managed an ISP's London Data Centres for 3 years as their core network engineer and architect. I have installed new devices and managed existing devices for them.
If you have any questions or would like to discuss this further please don't hesitate to contact me.
Thanks,
Shahzad
