Exemplo: Configuração da política de seleção de backup para o protocolo IS-IS
Este exemplo mostra como configurar a política de seleção de backup para o protocolo IS-IS.
Quando você habilita políticas de seleção de backup, o Junos OS permite a seleção de LFA com base nas regras de política e atributos dos links e nós na rede. Esses atributos são admin-group, srlg, largura de banda, tipo de proteção, métrica, vizinho e tag de vizinho.
Requisitos
Este exemplo usa os seguintes componentes de hardware e software:
Oito roteadores que podem ser uma combinação de roteadores de borda multisserviços da Série M, plataformas de roteamento universal 5G da Série MX e roteadores de núcleo da Série T
Junos OS Release 14.1 ou posterior em todos os dispositivos
Antes de começar:
Configure as interfaces do dispositivo.
Configure IS-IS.
Visão geral
A partir do Junos OS Release 14.1, o algoritmo de seleção ou critérios de seleção alternativa sem loop padrão (LFA) pode ser substituído por uma política LFA. Essas políticas estão configuradas para cada destino (IPv4 e IPv6) e uma interface de próximo salto primária. Essas políticas de backup aplicam a seleção de LFA com base em atributos de grupo de administradores, srlg, largura de banda, tipo de proteção, métrica, vizinho e etiqueta de vizinhos do caminho de backup. Durante a computação de caminho mais curto (SPF), cada atributo (nós e link) do caminho de backup, armazenados por next-hop de backup, é acumulado pelo IGP. Para as rotas criadas internamente pelo IGP, o conjunto de atributos de cada caminho de backup é avaliado em relação à política configurada para cada destino (IPv4 e IPv6) e uma interface primária de next-hop. O primeiro ou o melhor caminho de backup são selecionados e instalados como o próximo salto de backup na tabela de roteamento. Para configurar a política de seleção de backup, inclua a backup-selection declaração de configuração no nível de [edit routing-options] hierarquia. O show backup-selection comando exibe as políticas configuradas para uma determinada interface e destino. O display pode ser filtrado em um determinado destino, prefixo, interface ou sistemas lógicos.
Topologia
Nesta topologia, a política de seleção de backup está configurada no dispositivo R3.

Configuração
Configuração rápida da CLI
Para configurar este exemplo rapidamente, copie os seguintes comandos, cole-os em um arquivo de texto, remova qualquer quebra de linha, altere os detalhes necessários para combinar com a configuração da sua rede e, em seguida, copie e cole os comandos no CLI no nível de [edit] hierarquia.
