Please log in for more thread options I'm trying to connect two routers (7206 and 1700) via a serial interface over IP. Currently the serial communicates perfectly via IPX. I've just confgured ip addresses on both sides with a /30 mask and encapsulation is PPP but they cannot ping each other. I even tried HDLC but the IP stack on the interface cannot even open. I have attached the "show interface" command output of both routers: 1700 Router Serial1/0 is up, line protocol is up Hardware is CD2430 in sync mode Description: LINK TO SAFEX Internet address is 192.168.15.70/30 MTU 1500 bytes, BW 128 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 5/255 Encapsulation PPP, loopback not set Keepalive set (10 sec) DTR is pulsed for 4294967 seconds on reset, Restart-Delay is 541942 secs LCP Open Closed: CDPCP Open: IPXCP Last input 00:00:01, output 00:00:01, output hang never Last clearing of "show interface" counters 1w5d Queueing strategy: fifo Output queue 0/40, 0 drops; input queue 0/75, 0 drops 5 minute input rate 4000 bits/sec, 2 packets/sec 5 minute output rate 1000 bits/sec, 3 packets/sec 489253 packets input, 111702134 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0 throttles 1110 input errors, 681 CRC, 0 frame, 0 overrun, 0 ignored, 429 abort 599055 packets output, 25929293 bytes, 0 underruns 0 output errors, 0 collisions, 39 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions DCD=up DSR=up DTR=up RTS=up CTS=up 7206 Router SAFEX-7200-2#sh int s3/0:10 Serial3/0:10 is up, line protocol is up Hardware is Multichannel E1 Description: "Market Traders, Tim Gibson #57-03048-00" Internet address is 192.168.15.69/30 MTU 1500 bytes, BW 64 Kbit, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation PPP, crc 16, CRC 16, Data non-inverted Keepalive set (10 sec) LCP Open Open: IPXCP Last input 00:00:14, output 00:00:00, output hang never Last clearing of "show interface" counters 10:49:38 Input queue: 0/75/0 (size/max/drops); Total output drops: 0 Queueing strategy: weighted fair Output queue: 0/1000/64/0 (size/max total/threshold/drops) Conversations 0/4/16 (active/max active/max total) Reserved Conversations 0/0 (allocated/max allocated) 5 minute input rate 0 bits/sec, 0 packets/sec 5 minute output rate 0 bits/sec, 0 packets/sec 60631 packets input, 3053947 bytes, 0 no buffer Received 0 broadcasts, 0 runts, 0 giants, 0* throttles 0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 42071 packets output, 13260031 bytes, 0 underruns 0 output errors, 0 collisions, 0 interface resets 0 output buffer failures, 0 output buffers swapped out 0 carrier transitions no alarm present Timeslot(s) Used:10, subrate: 64Kb/s, transmit delay is 0 flags | |||||||||||||||||||

ip routing is activated on both routers. No ACL on both routers and our local TELCO tested the line and it passed 100%. Could it be the IOS maybe? | |||||||||||||||||||

Check the timeslots configured on both sides of the link and make sure that they are configured the same. Then run a show controllers s1/0 to make sure that the clocking is set properly. > I'm trying to connect two routers (7206 and 1700) via a serial
