O MPLS é disponibilizado para suportar várias interfaces físicas. Essas interfaces incluem ATM, POS e SRP. Essas interfaces são tipicamente usadas para conexões de backbone devido ao seu suporte de alta largura de banda. O recurso VPN MPLS permite que os provedores de serviços interconectem vários locais sem a necessidade de ATM, POS ou SRP no lado do cliente.
Há duas implementações de MPLS sobre ATM. Um deles é o uso de VPI (Virtual Path Identifier, identificador de caminho virtual) e VCI (Virtual Channel Identifier, canal virtual identificado) como o rótulo que também é conhecido como MPLS sobre ATM "baseado em célula". Esta implementação está documentada em RFC 3035 . A segunda implementação ATM é o uso do "cabeçalho de calço" MPLS, também conhecido como MPLS sobre ATM baseado em pacotes. Esse cabeçalho de calço é inserido entre os cabeçalhos das Camadas 2 e 3. O formato do cabeçalho do shim é documentado em RFC 3032 . Esta configuração de exemplo é baseada na implementação do "cabeçalho de shim" para a interface ATM.
Packet over Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) é uma tecnologia que coloca a camada IP diretamente acima da camada SONET. Elimina a sobrecarga necessária para executar IP sobre ATM sobre SONET. O POS suporta vários formatos de encapsulamento. Esses são PPP, HDLC e Frame Relay. O cabeçalho shim é usado para fornecer suporte a MPLS. Esta configuração de exemplo usa o encapsulamento HDLC padrão em interfaces Cisco POS.
O protocolo de reutilização espacial (SRP - Spatial Reuse Protocol) é uma tecnologia da camada 2 que fornece resiliência no nível da camada 2. Ele também é executado sobre SONET/SDH. O suporte a MPLS é fornecido pela implementação do cabeçalho do shim.
Nesta seção, você encontrará informações para configurar os recursos descritos neste documento.

Este documento utiliza a seguinte configuração de rede:
Isso lista algumas considerações feitas na configuração de exemplo:
O exemplo de serviço de configuração de VPN MPLS roteia o EIGRP dos CEs. O bug da Cisco ID CSCds09932 (somente clientes registrados) introduziu o suporte EIGRP para VPN MPLS com o Cisco IOS Software Release 12.0(22)S. Ele foi portado para o Cisco IOS Software Release 12.2T através do bug da Cisco ID CSCdx26186 (somente clientes registrados) iniciando no Cisco IOS Software Release 12.2(15)T. A aplicação do mesmo VRF em várias instâncias do EIGRP não é suportada e pode travar o roteador. Uma verificação deste problema foi posteriormente integrada com a ID de bug da Cisco CSCdz40426 (somente clientes registrados) . Consulte Suporte de VPN MPLS para EIGRP Entre a Borda do Provedor e a Borda do Cliente para saber mais sobre o suporte de VPN MPLS para EIGRP.
O sistema autônomo EIGRP é o mesmo em ambos os roteadores CE. O sistema autônomo BGP é o mesmo em ambos os roteadores PE.
O backbone MPLS é baseado em interfaces POS, ATM e SRP e configurado com OSPF (Open Shortest Path First) e MP-BGP. A conexão entre PE e CE é Fast Ethernet.
