Hi All,
We are redesigning the Management of of offices network devices.
network is like below
Vlan 300-----SW--10.1.1.1----------10.1.1.2 Router----WAN
we will configure reverse static router for 192.168.1.0/24 in router.
Option 1
- User separate management vlan i.e. 300( 192.168.1.0/24)for Switches access.
- Use loopback 192.168.2.1/32 router management.
But in this case we will be using 2 different subnets for offices network devices management.
Option 2
- User separate management vlan i.e. 300( 192.168.1.0/24)for Switches access.
- Create loopback 192.168.1.1/32 for router management and rest of IP for switch management.
-Advertise both 192.168.1.0/24 and 192.168.1.1/32 in BGP, if Switch goes then at least we can access router on 192.168.1.1
Do you think option 2 is feasible solution, if we want to use single management subnet for network devices?

Option 2 not correct' the same IP subnet can not be in different l3 Device that interconnect by l3 link.
So you need to use op1

@MHM Cisco World can you shed some light what issue can occur using option 2 in Network?

IP overlapping in your network
Two devices not direct connect using same subnet
That not correct.

I want when my switches goes down, then also I can access of routers on loopback
I am just trying to figure out what can be issue with below config in production environment?
RTR--10.1.1.1-------------10.1.1.2 SWT01
RTR01
int loopback
ip addresss 192.168.1.1/32
Router bgp 300
network 192.168.1.1/32
Network 192.168.1.0/24
ip route 192.168.1.0/24 next-hop 10.1.1.2 track xxx
SWT01
interface vlan 300
ip addresss 192.168.1.3/24
