Titolo: Frame-relay

Ciao a tutti,
sto installando x la prima volta (scusate se chiedo cose banali) una rete in
frame-relay con linee cdn/adsl/hdsl.
Ho installato il router centrale (un 2620 con 1 seriale su linea cdn) e 1
router di sede (1720 su hdsl) ma non comunicano; attivando il debug
frame-relay lmi, ho visto che da entrambe le parti mi da' il pvc giu' sui 2
coll in hdsl (inizialmente perche' il modem telecom era staccato, ok).
Sui router ho impostato: encapsulation frame-relay ietf, lmi type auto - ho
creato le sub-interface punto-punto ed ho associato il dlci assegnato..
manca qualcosa x lavorare con hdsl o è un problema telecom??
qs il debug del router di sede:
00:17:06: Serial0(in): Status, myseq 102
00:17:06: RT IE 1, length 1, type 0
00:17:06: KA IE 3, length 2, yourseq 180, myseq 102
00:17:06: PVC IE 0x7 , length 0x6 , dlci 30, status 0x0 , bw 32000
00:17:16: Serial0(out): StEnq, myseq 103, yourseen 180, DTE up
00:17:16: datagramstart = 0x198ECF4, datagramsize = 13
00:17:16: FR encap = 0xFCF10309
00:17:16: 00 75 01 01 01 03 02 67 B4
e qs del centrale:
03:32:41: Serial0/0(in): Status, myseq 97
03:32:41: RT IE 1, length 1, type 0
03:32:41: KA IE 3, length 2, yourseq 241, myseq 97
03:32:41: PVC IE 0x7 , length 0x6 , dlci 20, status 0x2 , bw 32000
03:32:41: PVC IE 0x7 , length 0x6 , dlci 30, status 0x0 , bw 32000
03:32:41: PVC IE 0x7 , length 0x6 , dlci 40, status 0x0 , bw 32000
03:32:41: PVC IE 0x7 , length 0x6 , dlci 50, status 0x2 , bw 32000
03:32:51: Serial0/0(out): StEnq, myseq 98, yourseen 241, DTE up
03:32:51: datagramstart = 0x1C00854, datagramsize = 13
03:32:51: FR encap = 0xFCF10309
03:32:51: 00 75 01 01 01 03 02 62 F1
ciao e grazie x l'attenzione

se non ricordo male l' lmi-type e' ansi
posta la configurazione, mascherando gli IP..
ciao


ti allego i file di conf dei 2 router.. gli ip sono privati, la vpn e'
telecom..
p.s. ma se l'lmi e' sbagliato non dovrei ne' vedere i pacchetti che mi manda
il dte ne' vedere i gli altri 2 pvc "up"?
p.p.s. se trovi qlc magagna dimmi pure.. io ho copiato la conf di una rete
di un nostro cliente, ma e' la prima frame che installo.... e purtroppo non
ho colleghi in azienda che seguono router, xcio' mi tocca arrangiarmi...
grazie mille x l'interessamento!
