1. ATM Frame Relay virtual channel trunking Unlike standard ATM Frame Relay circuits which always have two endpoints 1 1 circuits virtual channel trunking allows N 1 circuits With virtual channel trunking a circuit can have more than two endpoints as long as multiple endpoints are designated as host links and only one endpoint is designated as a trunk link The system aggregates traffic from multiple host links onto one trunk link creating an N 1 circuit as shown in Figure 5 3 Figure 5 3 N 1 circuit between multiple Frame Relay hosts and an ATM trunk Frame Relay Host links Trunk link With virtual channel trunking the circuit endpoints can include multiple Frame Relay DLCI interfaces and an ATM VPI VCTI interface as long as only one trunk link is specified When the system receives upstream traffic from a host link it learns the host s MAC address and then forwards the data to the trunk link interface When the system receives downstream traffic from the trunk link it uses the destination MAC address to transmit the packets on the appropriate host link Current limitations of virtual channel trunking In the current software version the virtual channel trunking implementation is subject to the following limitations e Only one ATM endpoint can be defined per circuit e Broadcast and multicast packets from the trunk link are not forwarded to the host links of the circuit e Packets from the indivi
