NOTE: The built-in Gigabit Ethernet PIC on an M7i router does not support
extended VLAN VPLS encapsulation.
—Use in a VPLS setup when a CE device is connected to a PE router over
ethernet-vpls-fr
a time-division multiplexing (TDM) link. This encapsulation type enables the PE
router to terminate the outer layer 2 Frame Relay connection, use the 802.1p bits
inside the inner Ethernet header to classify the packets, look at the MAC address
from the Ethernet header, and use the MAC address to forward the packet into a
given VPLS instance.
—Use Frame Relay encapsulation on CCC circuits. When you use this
frame-relay-ccc
encapsulation type, you can configure the
—Use Frame Relay ether type encapsulation for compatibility with
frame-relay-ether-type
Cisco Frame Relay. The physical interface must be configured with
flexible-frame-relay encapsulation.
frame-relay-ether-type-tcc
Relay on TCC circuits to connect different media. The physical interface must be
configured with flexible-frame-relay encapsulation.
frame-relay-ppp —Use PPP over Frame Relay circuits. When you use this encapsulation
type, you can configure the
frame-relay-tcc —Use Frame Relay encapsulation on TCC circuits for connecting different
media. When you use this encapsulation type, you can configure the
—For adaptive services interfaces only, use GRE fragmentation
gre-fragmentation
encapsulation to enable fragmentation of IPv4 packets in GRE tunnels. This
encapsulation clears the do not fragment (DF) bit in the packet header. If the packet's
size exceeds the tunnel's maximum transmission unit (MTU) value, the packet is
fragmented before encapsulation.
multilink-frame-relay-end-to-end
is used only on multilink, link services, and voice services interfaces and their
constituent T1 or E1 interfaces, and is supported on LSQ and redundant LSQ interfaces.
—Use MLPPP encapsulation. This encapsulation is used only on multilink,
multilink-ppp
link services, and voice services interfaces and their constituent T1 or E1 interfaces.
ppp-over-ether —Use PPP over Ethernet encapsulation to configure an underlying Ethernet
interface for a dynamic PPPoE logical interface on M120 and M320 routers with
Intelligent Queuing 2 (IQ2) PICs, and on MX Series routers with MPCs.
ppp-over-ether-over-atm-llc
only) For underlying ATM interfaces, use PPP over Ethernet over ATM LLC
encapsulation. When you use this encapsulation type, you cannot configure the
interface address. Instead, configure the interface address on the PPP interface.
