Ciao a tutti,

sto rifacendo in dynamips un lab ripng che ho trovato su "Routing TCP/IP vol1" di Doyle a pagina 226.
In pratica mostra come filtrare le update usando processi ripng multipli.
Sto avendo strani risultati con le rotte propagate dal processo ripng "two" che gira tra R2, R3 e la L0 di R4.
Sembra che R2 non installi la L0 di R4 (4000::/64) nella tabella di routing.

R1#sh ipv6 ro rip
R 2000:24::/64 [120/2]
via FE80::C801:BFF:FE98:8, FastEthernet0/0
R 4001::/64 [120/3]
via FE80::C801:BFF:FE98:8, FastEthernet0/0
---------------------------------------------------
R2#sh ipv6 ro rip
R 3000::/64 [120/2]
via FE80::C802:BFF:FE98:8, FastEthernet1/0
R 3001::/64 [120/2]
via FE80::C802:BFF:FE98:8, FastEthernet1/0
R 4001::/64 [120/2]
via FE80::C803:BFF:FE98:38, FastEthernet2/0
---------------------------------------------------
R3#sh ipv6 ro rip
R 2000:24::/64 [120/2]
via FE80::C801:BFF:FE98:1C, FastEthernet0/0
---------------------------------------------------
R4#sh ipv6 ro rip
R 2000:12::/64 [120/2]
via FE80::C801:BFF:FE98:38, FastEthernet2/0
R 3000::/64 [120/3]
via FE80::C801:BFF:FE98:38, FastEthernet2/0
R 3001::/64 [120/3]
via FE80::C801:BFF:FE98:38, FastEthernet2/0


Ma dal debug vedo che la rotta viene ricevuta da R2

R2#
*Aug 4 21:46:58.887: RIPng: response received from FE80::C803:BFF:FE98:38 on FastEthernet2/0 for two
*Aug 4 21:46:58.891: src=FE80::C803:BFF:FE98:38 (FastEthernet2/0)
*Aug 4 21:46:58.895: dst=FF02::9
*Aug 4 21:46:58.895: sport=527, dport=527, length=52
*Aug 4 21:46:58.899: command=2, version=1, mbz=0, #rte=2
*Aug 4 21:46:58.899: tag=0, metric=1, prefix=2000:24::/64
*Aug 4 21:46:58.899: tag=0, metric=1, prefix=4000::/64


Sempre dal debug vedo che non viene inviata da R2 ad R3; e dal ripng database vedo chiaramente la rotta presente ma non installata.

R2#sh ipv6 rip database
RIP process "one", local RIB
2000:12::/64, metric 2
FastEthernet0/0/FE80::C800:BFF:FE98:8, expires in 165 secs
2000:24::/64, metric 2
FastEthernet2/0/FE80::C803:BFF:FE98:38, expires in 157 secs
4001::/64, metric 2, installed
FastEthernet2/0/FE80::C803:BFF:FE98:38, expires in 157 secs
RIP process "two", local RIB
2000:23::/64, metric 2
FastEthernet1/0/FE80::C802:BFF:FE98:8, expires in 157 secs
2000:24::/64, metric 2
FastEthernet2/0/FE80::C803:BFF:FE98:38, expires in 155 secs
3000::/64, metric 2, installed
FastEthernet1/0/FE80::C802:BFF:FE98:8, expires in 157 secs
3001::/64, metric 2, installed
FastEthernet1/0/FE80::C802:BFF:FE98:8, expires in 157 secs
4000::/64, metric 2
FastEthernet2/0/FE80::C803:BFF:FE98:38, expires in 155 secs



Qualcuno riesce a darmi una mano? Sotto riporto la configurazione di dynamips e delle macchine.
Grazie in anticipo e scusate per il post lunghetto.
