Hi..Everyone..
I was confused by PPP & LAPB's configuration
Who know the right method ??
---------
Diagram
---------
R1-(S1 7.7.7.1)----(S0 7.7.7.3)-R3
----------
Question
----------
A>Configure PPP between R1 & R3
=>is this a general ppp-configuration ?
B>If a packet is lost due to a hit,make sure that the sending router
retransmit the pascket
=> this is related with a LAPB !
But how can i find a soultion which satisfies the A> & B > ??
C>Use a stac-compression..
-----------------
First Solution
-----------------
R1>
interface Serial1
ip address 7.7.7.1 255.255.255.0
encapsulation lapb dce pppoe **> is right ??
no ip mroute-cache
clockrate 4000000
compress stac
R3>
interface Serial0
ip address 7.7.7.3 255.255.255.0
encapsulation lapb
no ip mroute-cache
compress stac
=> But when i can ping each other, if failed !!!
Who know the reason ??
R1#ping 7.7.7.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 7.7.7.1, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
-----------------
Second Solution
-----------------
R1>
interface Serial1
ip address 7.7.7.1 255.255.255.0
encapsulation ppp
no ip mroute-cache
clockrate 4000000
compress stac
R3>
interface Serial0
ip address 7.7.7.3 255.255.255.0
encapsulation ppp
no ip mroute-cache
compress stac
=> i can ping each other, if successed !!!
R1#ping 7.7.7.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 7.7.7.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 4/7/8 ms
=> But the below question is not solved in my 2'nd solution..
"B>If a packet is lost due to a hit,make sure that the sending router
retransmit the pascket'
=> How can i change my 1'st or 2'nd solution to satisfy the Question A,B
and C at same time ??
