For a router supporting PPPoE, you can derive the source address from a specified
interface—for example, the loopback interface,
address—for example,
192.168.1.2
number and have a configured IP address. To derive the source address and assign the
destination address, include the
[edit interfaces pp0 family inet]
[edit interfaces pp0 family inet]
unnumbered-address interface-name destination address;
You can have the PPPoE client router obtain an IP address by negotiation with the remote
end. This method might require the access concentrator to use a RADIUS authentication
server. To obtain an IP address from the remote end by negotiation, include the
statement:
negotiate-address
negotiate-address;
You can configure the maximum transmission unit (MTU) size for the protocol family.
Specify a range from 0 through 5012 bytes. Ensure that the size of the media MTU is
equal to or greater than the sum of the protocol MTU and the encapsulation overhead.
To set the MTU, include the
hierarchy level:
| mpls) ]
[edit interfaces pp0 family (inet | inet6 | mpls) ]
mtu bytes;
To verify a PPPoE configuration, you can issue the following operational mode commands:
show interfaces f0/0/port extensive
show interfaces pp0
show pppoe interfaces
show pppoe statistics
For more information about these operational mode commands, see the Junos OS
Interfaces Command Reference.
