Alright!! After many many months of frustration with what I thought was a problem with ppp encap, it turned out to be something else. As Stuart correctly pointed me to this url (which I have no idea why I did not look it up earlier) the problem lies with using LDN along with the SPID #'s. Thank you Stuart for this one.
I tested it first using just plain HDLC, then with plain PPP, then added ppp auth chap, then ppp chap hostanme and then with finally what I presumed to be the culprit, ppp multilink. But lo behold!! all of these worked with NO problem when the LDN # is not specified along with the SPID #. Here is my config: Current configuration : 455 bytes ! interface BRI0 ip address 9.9.9.1 255.255.255.0 encapsulation ppp ip ospf network broadcast ip ospf demand-circuit dialer map ip 9.9.9.2 broadcast 5553000 dialer load-threshold 1 either dialer-group 1 isdn switch-type basic-ni isdn spid1 0555100001 isdn spid2 0555200001 cdapi buffers regular 0 cdapi buffers raw 0 cdapi buffers large 0 ppp authentication chap ppp chap hostname backup ppp chap password 7 121A061902 ppp multilink end R8#ping 9.9.9.2 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 9.9.9.2, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 36/38/40 ms R8# Hope this helps others like me with similiar problems >From: "Stuart Potts" >Reply-To: "Stuart Potts" >To: [EMAIL PROTECTED] >Subject: RE: Isdn error with PPP - Why always??
