Example: Configuring SONET/SDH Interfaces
SONET/SDH interfaces can use either PPP or Cisco
HDLC encapsulation. Use PPP if you are running Cisco IOS Release 12.0
or later. If you need to run Cisco HDLC, the JUNOS software automatically
configures an ISO family MTU of 4469 in the routing platform. This
is due to an extra byte of padding used by Cisco. The following configuration,
which uses PPP encapsulation, is sufficient to get a SONET/SDH OC3
or OC12 interface up and running:
- [edit interfaces]
- so-fpc/pic/port {
- encapsulation ppp;
-
- unit 0 {
-
- family inet {
-
- address local-address {
- destination remote-address;
- }
- }
- }
- }
