I'm working with an existing Nexus 7K BGP config running BFD and an operational peer to another Nexus 7k on this network.
I'm adding a Cisco ASR 1001 into the BGP peering and all appears to be fine but I need some direction on the BFD authentication configuration to match the Nexus 7k configuration.
On the Nexus 7k interface the following line is configured
bfd authentication Keyed-SHA1 key-id 1 hex-key 12345678909876543212
On the ASR I need the equivalent line configured.
The part I'm stuck in is trying to find a match option for the hex-key during the key chain configuration part but all I get is a key-string option
I'm using this document to configure the ASR side as the Nexus is already configured.
Any direction is greatly appreciated!
The config on the ASR should be something like this under the interface or sub-interface
bfd interval 300 min_rx 300 multiplier 3
Thanks for the response how about the authentication portion?
Have not done authentication with BFD before but maybe something like this to match the key string with the Nexus
Device# configure terminal
Device(config)# key chain chain1
Device(config-keychain)# key 1
Device(config-keychain-key)# key-string 12345678909876543212
