I've been tasked with restoring both RSPs on&nbsp;router, and while having backup configs, licenses, and snmp folders have all been prescribed, I'm very concerned about the fact that being forced to generate a new rsa host key will likely get in the way of operations. I find it hard to accept that the router identity is ultimately changed because we only allow ssh connections and every user/tool/whatever will likely be interrupted when the new host key is put in place, and we'll be accosted with questions. There needs to be a way to do this. Can anyone advise? Thanks!</P> Fri, 21 Feb 2020 13:38:46 GMT https://community.cisco.com/t5/network-security/how-to-backup-and-or-restore-rsa-host-key-for-ios-xr/m-p/2794289#M915621 tlewisflood 2020-02-21T13:38:46Z https://community.cisco.com/t5/network-security/how-to-backup-and-or-restore-rsa-host-key-for-ios-xr/m-p/2794290#M915623 <P>Hi - I have same issue.
