Dear All Expert,
Currently, i have a issue of the DLsw ER+ and i hope that DLSw+ Netpro Experts can highlight/advice my problem.
Please refer the diagram - dlsw+.jpg first.
Early, my network did configure the #bridge-group 1 in both Fast-Ethernet of Router A and B, but it suffer the common dlsw issue
â¢Unreliable Local Reachability Information
â¢Undetected Looping Explorers
After removing one #bridge-group 1 from Router B Fast-Ethernet, the network become stable already.
Now i still look for the DLsw Ethernet redundancy solution (Purpose = Router A as primary and Router B will take over role A
in case Router A down), and do some research.
But, it look like my problem more suitable to use cisco solution << URL 2 - Figure 6 DLSw+ with Ethernet Redundancy Enabled >>
Example from URL 2:
dlsw local-peer peer id 10.2.24.2
dlsw remote-peer 0 tcp 10.2.17.1
ip address 126.96.36.199 255.255.255.0
dlsw transparent redundancy-enable 9999.9999.9999
dlsw local-peer peer-id 10.2.24.3
dlsw remote-peer 0 tcp 10.1.12.1
ip address 188.8.131.52 255.255.255.0
dlsw transparent redundancy-enable 9999.9999.9999 master priority 1
dlsw transparent timers sna 1500
Now my concerns are
1. It is really suitable to use the URL2 solution ? or Dlsw passive and backup-peer are better ?
2. If using URL2 solution, is it following the multicast MAC-address 9999.9999.9999 ? How to choose the MAC address ?
3. Should i still put the #bridge-group 1 command into both Fast-Ethernet of Router A and B ? If still working without the #bridge-group 1 command ?
4. Just review the URL3, and it is more complicated. Because it has to configure each MAC-address in the Fast-Ethernet and #dlsw transparent Map. Is it neccessary to use #dlsw transparent map or the URL2 will do it as well.
FYI - the current dlsw config of router A and B
dlsw local-peer peer-id 184.108.40.206
dlsw timer explorer-wait-time 3
dlsw timer explorer-delay-time 1
dlsw timer connect-timeout 600
dlsw timer local-connect-timeout 15
dlsw rsvp default
dlsw remote-peer 0 tcp 220.127.116.11 host-netbios-out XXX
dlsw remote-peer 0 tcp 18.104.22.168
dlsw remote-peer 0 tcp 22.214.171.124
dlsw bridge-group 1
bridge-group 1 (only in router A now)
Please kindly help it.
