Gerenciar aviso do BGP (v2)
Quando você cria prefixos anunciados públicos v2 e prefixos delegados públicos v2, eles não são anunciados automaticamente. Você escolhe quando anunciar
ou remover os prefixos.
Especificações
Anunciar um prefixo público anunciado anuncia todo o prefixo público anunciado na Internet.
O anúncio de um prefixo delegado público informa que ele
está no Google Cloud.
É possível anunciar um prefixo público delegado sem anunciar o prefixo público
anunciado pai. Nessa configuração, o prefixo público delegado
é anunciado no Google Cloud e não é anunciado para a Internet.
É necessário anunciar pelo menos um prefixo público delegado antes de anunciar o prefixo público anunciado pai.
Não será possível retirar o aviso de um prefixo público delegado se ele for o
único prefixo público delegado anunciado para o prefixo público
pai anunciado. Primeiro, retire o prefixo público anunciado principal e,
em seguida, cancele o prefixo público delegado.
