Hi All,
I try to connect 1 ex3200-48t [11.4R5.5] with mx-10003 17.4R2-S4.1.
Note: I can not modify any configuration on the ex3200-48t i can only play with the mx.
Problem: I need to create an OSPF peering between them but i got this error on the mx
Bla@bla.bla> show log ospf-debug | match mtu
Nov 6 17:50:16.370895 options 0x50, i 1, m 1, ms 1, r 0, seq 0xd974d59a, mtu 8982

Nov 6 17:50:20.710752 options 0x50, i 1, m 1, ms 1, r 0, seq 0xd974d59a, mtu 8982
On the ex3200-48t (IP x.x.x.4) I see
set interfaces vlan mtu 9000
set interfaces vlan unit 350 family inet mtu 8982
On the mx I try to run the following
bla@bla# show | compare
[edit interfaces]
+ xe-1/1/10 {
+ mtu 9000;
+ }
[edit]
bla@bla# commit
and then
bla@bla# commit check
[edit interfaces xe-1/1/10:0 unit 350 family]
'inet'
Family MTU 8982 is too large relative to device MTU 1518; Protocol overhead should be 18
error: configuration check-out failed
[edit]
bla@bla#
Of course L3 interface xe-1/1/10:0 unit 350 on MX is connected to L3 interface vlan unit 350 on ex. Direct connection.
Any idea how can i fix this?
Thanks.
