configurar bgp - cisco 2800 series

[felix]

Olá.

Preciso configurar um bgb em um roteador cisco, mas estou com diversas dúvidas:

A configuração que me foi passada é esta que segue abaixo (devidamente editado por questões de segurança):

porta: 0/1/0.1/2/4/2:1
roteador aaaa01.aaa
ip serial embratel 111.111.111.111 mascara 255.255.255.252
ip serial cliente 222.222.222.222 mascara 255.255.255.252

As informações de meu router cisco seguem abaixo (julgo estar informando o necessário, caso precisem de outra informação para me ajudar, basta pedirem

Resumindo: não tenho a mínima idéia se devo ou como configurar o item porta: 0/1/0.1/2/4/2:1 conforme me foram passadas as instruções, em quais interfaces configurar os ip's e se tenho que fazer mais alguma coisa para ativar o bgp.

Li e estou novamente relendo este material: Open Source Security1osPassosCisco.pdf mas como é a primeira vez que vejo um roteador cisco esta questão do bgp me deixa muito confuso, sem falar que este outro material Cisco IOS Release 12.0 Network Protocols Configuration Guide, Part 1 - Configuring BGP - Cisco Systems para mim está realmente muito complexo, travei logo neste item: Cisco IOS Release 12.0 Network Protocols Configuration Guide, Part 1 - Configuring BGP - Cisco Systems

Toda ajuda é bem vinda. Obrigado desde já

Faz um Curso da Cisco cara, pois BGP é pra quem sabe.
Pois uma config ruim pode te gerar um dano muito pior.

Se tiver como usar mikrotik aqui esta o passo a passo com explicações. Vc vai fechar BGP FULL?

Faz um Curso da Cisco cara, pois BGP é pra quem sabe.
Pois uma config ruim pode te gerar um dano muito pior.

Pensei na possibilidade de fazer um curso, porém o custo benefício para mim não compensaria. Pois em anos trabalhando com redes foi a primeira vez em que precisei fazer algo em um roteador Cisco. E não sei quando precisarei fazê-lo novamente, caso pague caro em um curso e não pratique, acabarei por esquecer e ficar desatualizado (na verdade minha área de atuação não é especificamente redes).

De toda forma, obrigado a quem se disponibilizou em ajudar, acabamos por pagar alguem para fazer as configurações necessárias.
