Hostname appears different on IOS router

[DuBu]

Hi

We have 2  8300 series routers at a given location.

1. Router 1 -- ABC

2. Router 2 -- XYZ

When I ssh to router "ABC" using hostname it displays the prompt as -- "XYZ" >

When I check the running config in this scenario, the hostname mentioned shows "XYZ".

However , when i ssh to "ABC" using its ip address it displays the correct prompt -- "ABC" >

When I check the running config, the hostname displays "ABC" which is correct.

I wanted to understand the difference in behavior when trying to ssh using Hostname vs when ssh using IP address

Sorry @MHM Cisco World , could you please explain what you meant?

how you can access to router via SSH ? you need password, how you dd this password in router ?

MHM

[DuBu]

yes, i do enter the password in both scenarios, i.e.  when I ssh to the router using hostname and also when i ssh to the router using IP address.

this password config in router under ""line vty"" or via ""username xxx password xxx""?

I dont see any ""username xxx password xxx"" config...There is password info mentioned under "line vty" config as follows

line vty 0 4
access-class vty_access_in in vrf-also
password 7 083A5F173615543A333317172B6120
transport preferred none
transport input ssh
transport output telnet ssh
line vty 5 15
access-class vty_access_in in vrf-also
password 7 083A5F173615543A333317172B6120
transport preferred none

Hi @DuBu ,

If you get to the wrong device when using the host name and to the correct device when using the IP address then it is most likely a DNS issue. Can you check what the is the IP address linked to host "ABC" and change it to correct the issue.

You can use DNS tools like dig, nslookup, host, etc to verify the host name to IP address mapping.

Hello @DuBu ,

check on OS shell how hostname is solved using

nslookup <ABC>

as suggested you may be facing a wrong DNS entry

Hope to help

Hello
Curious where are you initiating the ssh connection?
