Para configurar a BFD em um Arista EOS, use o seguinte comando (os valores mostrados são exemplos):
int NAME
bfd interval 1000 min_rx 1000 multiplier 5
router bgp 65201
neighbor 169.254.88.81 bfd
neighbor 169.254.149.193 bfd
Para ver mais configurações e exemplos de configuração do Arista BFD, consulte a
Seção 37.2: Configuração BFD
na documentação do Arista.
Cisco ASA
Para ver exemplos de configuração do Cisco ASA, consulte
Roteamento de detecção de encaminhamento bidirecional
(em inglês) na documentação da Cisco. A configuração do BGP é idêntica à configuração do IOS/IOS-XE mais adiante neste documento.
Cisco ASR
Para ver o status da BFD, use o seguinte comando no nível superior da
configuração do Cisco AS:
show bfd neighbors 169.254.44.6 details
Para configurar a BFD em um Cisco ASR, use o seguinte comando (os valores mostrados são exemplos):
