Hello @all.

i hope you're fine.

i have one 5 sites and each site use S12700 as backbon switch .

i want to implement vpls solution from one ISP between our each sites.

site 1 is hub site . the other site will take the service from this site.

 site 1 use : vlanif 90 with 192.168.15.90 24

site 2 use : vlanif 81 with 192.168.15.91 24

site 3 use : vlanif 82 with 192.168.15.92 24

site 4 use : vlanif 83 with 192.168.15.93 24

eache site use ospf process 1 with network 192.168.15.0 0.0.0.255


my problem is site 1, site 2 and site 3 can ping each other and ping each LAN . but site 4 can only ping the ip address wan of site 1. site 4 can not ping LAN of site 1, site 2 and site 3.

i use the same process and i don't understand why site 4 can not ping LAN of others site.


this is my configuration in each site .


site 1:

sysname site1

#

vlan batch 90

#

interface loopBack 0

ip address 192.168.2.1

#

interface Vlanif90

 ip address 192.168.12.90 255.255.255.0

ospf network-type p2mp

ospf p2mp-mask-ignore

#

interface 10GE1/7/0/15

porswicth

 port link-type trunk

 port trunk allow-pass vlan 90

quit


ospf 1 router-id 192.168.2.1

 area 0.0.0.0

 port link-type trunk

 port trunk allow-pass vlan 91

quit

 area 0.0.0.0

network 192.168.12.0 0.0.0.255

network 192.168.2.4 0.0.0.0



site 3:

sysname site3

#

vlan batch 92

#

interface loopBack 0

ip address 192.168.2.9

#

interface Vlanif92

 ip address 192.168.12.92 255.255.255.0

ospf network-type p2mp

ospf p2mp-mask-ignore

#

interface g1/1/23

porswicth

 port link-type trunk

 port trunk allow-pass vlan 92

quit


ospf 1 router-id 192.168.2.9

 area 0.0.0.0

network 192.168.12.0 0.0.0.255

network 192.168.2.9 0.0.0.0



site 4:

sysname site4

#

vlan batch 93

#

interface loopBack 0

ip address 192.168.2.19

#

interface Vlanif93

 ip address 192.168.12.93 255.255.255.0

ospf network-type p2mp

ospf p2mp-mask-ignore

#

interface g1/1/23

porswicth

 port link-type trunk

 port trunk allow-pass vlan 93

quit


ospf 1 router-id 192.168.2.19

 area 0.0.0.0

network 192.168.12.0 0.0.0.255

network 192.168.2.19 0.0.0.0


someone can help me to know exactly why site 4 can't ping LAN of Site 1 but can ping interface WAN of site 1.

for me i think it's ospf process failed or not correct.


thank you

Hi, friend!
My advice is as follows:
1. Check whether OSPF neighbor relationships are established between site 4 and other sites.
2. Can you use the broadcast network type?
3. Your IP addresses are in the same network segment, but the VLAN IDs used by you are different. Can you modify the IP addresses?
4. Check whether the OSPF neighbor routing table and LSDB table are normal.

friend, However, you can find that in the topology, the interfaces connected to the two devices use the same VLAN. Multiple interfaces on the switch can use different VLANs, but the interfaces connected to the two switches must use the same VLAN.
