As it is currently, BFD timers are per-peer only, meaning if I just want the same setting on 20 peers I need 20 separate peer statements; in a large environment, this doesn't scale. I'd like to propose that we additionally have a configuration node to set BFD defaults, something like:
protocols {
bfd {
defaults {
interval {
receive 50
transmit 50
}
source {
ipv4 {
address 192.168.253.1
interface dum0
}
ipv6 {
address fd52:d62e:8011:fffe:192:168:253:1
interface dum0
}
}
multihop {
ipv4 enable
ipv6 enable
}
}
}
}Arista EOS actually offers this as the only BFD configuration option:
ir01(config)#show run | i ^bfd bfd local-address 192.168.253.1 bfd local-address fd52:d62e:8011:fffe:192:168:253:1 bfd multihop interval 50 min_rx 50 multiplier 3
