Hi,friends,I want use PPP multilink binding 2 E1 interface,My device is cisco 7609 + SIP-400 + SPA-8XCHT1/E1, other side is H3C MSR 5060. After the configuration,I found the 2 E1 interfaces are UP UP , but the interface multilink is Down  Down?

Here is "show interface multilink 1" command execute,I found the LCP is "Initial":


cisco#show int multilink 1
Multilink1 is down, line protocol is down
  Hardware is multilink group interface
  Internet address is 1.1.1.1/8
  MTU 1500 bytes, BW 4096 Kbit, DLY 20000 usec,
     reliability 230/255, txload 1/255, rxload 1/255
  Encapsulation PPP, LCP Initial, multilink Open, loopback not set
  Keepalive set (10 sec)
  DTR is pulsed for 2 seconds on reset
  Last input never, output never, output hang never
  Last clearing of "show interface" counters 01:31:55
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: fifo
  Output queue: 0/40 (size/max)
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     298 packets input, 14168 bytes, 0 no buffer
     Received 0 broadcasts (0 IP multicasts)
     0 runts, 0 giants, 0 throttles
     13144 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort
     83 packets output, 1954 bytes, 0 underruns
     0 output errors, 0 collisions, 11 interface resets
     0 output buffer failures, 0 output buffers swapped out
     0 carrier transitions


My configuration is:


interface Multilink1
no ip address
ppp multilink
ppp multilink group 1
no cdp enable

interface Serial4/0/1:0
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1
!
interface Serial4/0/2:0
no ip address
encapsulation ppp
ppp multilink
ppp multilink group 1

I am glad to know that you have resolved the problem. Thank you for posting back and indicating that it was solved and what you did to solve it. It makes the forum more helpful when people can read about an issue and can also read what was the successful solution to the issue.

Hi Hou,


have you configured the time slots for each E1 interface?


controller E1 4/0/1 and 4/0/2
framing NO-CRC4
channel-group 1 timeslots 1-31

the cisco router receives a Configuration Request

that describes the parameters for the PPP multilink connection but it doesn't like it and sends back a configuration  reject


cisco(config-if)#e4/0/1:0 LCP: O CONFREJ  [REQsent] id 204 len 6


I = input received from neighbor

O = output sent to neighbor


on the  other side have you set a name for the bundle or any other additional parameter?


what is the output of

debug ppp multilink?


also useful is

sh ppp multilink



another note:

if you want to negotiate an IP address with IPCP you should use ip address negotiated in multilink interface instead of no ip address


Also if it is a C7600 you need to use two serial interfaces taken from the same SPA or PA but you are fine you are using two interfaces on same SPA.


Hope to help

Giuseppe

Dear giuslar:

Thanks for your answer,the debug message is out of the command "show ppp negotiate".

My router is 7609,and I use 2 E1 interface on the same SIP & SPA,there is nothing wrong. So I decide to check the other side's configuration.

I can't get the answer.

My configuration on the remote site is below ,the router is H3C MSR50 60:



display current-configuration
#
version 5.20, Release 1809P01, Basic
#
sysname R5060
#
interface Serial10/1
fe1 unframed
link-protocol ppp
ppp mp Mp-group 1
#
interface Serial10/2
fe1 unframed
link-protocol ppp
ppp mp Mp-group 1
#

interface Mp-group1
ip address 1.1.1.2 255.255.255.0
#



I tried debug the remote device,I found the LCP is Open first,then it changes Request,I don't know why!
