|
Estou com problema de "Descoberta e
Divulga��o"(protocolos ARP e RIP 2) de endere�os IP e suas m�scaras, em
roteadores CISCO 2510. A rede Corporativa � composta de v�rios roteadores ASN da
Bay Networks(Nortel) e apenas dois modelo 2510 da Cisco, e s�o exatamente esses
da Cisco que acredito serem os respons�veis pela propaga��o de endere�os com as
m�scaras incorretas( de Broadcasting).
Abaixo est�o o desenho do ramo da rede onde est� acontecendo o problema e
alguns textos de configura��o capturados nos roteadores.
