<DIV></DIV>>Hi guys/girls
<DIV></DIV>>
<DIV></DIV>>I am having a lot of problems making NLSP form up over frame rel
ay point =
<DIV></DIV>>to point sub interfaces. Everything else is fine, PPP, ATM, HDLC
, Token =
<DIV></DIV>>Ring and Ethernet all work fine!
<DIV></DIV>>
<DIV></DIV>>Basically sometimes it works, and others it doesnt.
<DIV></DIV>>
<DIV></DIV>>I have done lots of debugs, and it appears that 1 router is rece
iving =
<DIV></DIV>>Hellos but not sending any back
<DIV></DIV>>The link is configured with IPXWAN, and sometimes removing the I
PXWAN =
<DIV></DIV>>config and replacing it again lets the neighbors come up. I pres
umed =
<DIV></DIV>>this was because IPXWAN would retry and time out before my DLCI
got =
<DIV></DIV>>bound to the interface
<DIV></DIV>>
<DIV></DIV>>The layout is simple
<DIV></DIV>>
<DIV></DIV>>R2-----dlci40----FR.Switch-----dlci40-----R6
<DIV></DIV>>
<DIV></DIV>>The configs are simple, R2 is in 2 NLSP areas (100 and 200) and
R6 is =
<DIV></DIV>>just in area 200

it =
