Dear,
I have a problem after changing my CCR1036-12G-4S edge router to CCR1072.
I will show how it was my scenario and how it was.
edge router ccr1036
→ Sfp3-> concentrador1 ccr1036-> sfp1-> pppoe clients
→ Ether 3-> 2 concetrador ccr1036-> sfp1-> pppoe clients
→ Ether4-> concetrador 3 ccr1009->
sfp1-> pppoe clients
At the edge router SFP1 have a 1GB / s IP link to the carrier 1, spf2 have 1GB / s of the carrier 2.
OBS .: All GBICs are mikrotik dual LC 1GB / s singlemode
They were all in version 6.27 of OS router working 100%.
We hired a new link to a third operator 10GB / s with it, bought a ccr1072 to be able to meet the need of getting:
edge router ccr1036
→ Sfp + 4> concentrador1 ccr1036
→ Sfp-> pppoe clients
→ Sfp + 5> concetrador 2 ccr1036-> sfp1-> pppoe clients
→ Sfp + 6> concetrador 3 ccr1009->
sfp1-> pppoe clients
In sfp + 1 is the link 10GB / s with GBIC 10GB / s dual LC singlemode mikrotik
in sfp + 2 Is the 1G link / operator s 1 with GBIC mikrotik 1GB / s dual LC monmodo
in sfp + 3 is the 1GB link / s operator with 2 GBIC mikrotik 1GB / s dual LC monmodo
The part of the link is 100% operacional.O problem is in communication between concentrators using GBIC SFP Transceivers 1GB / s and edge using GBIC 1GB / s.
- the hub which is in the SFP port + 4 loses communication twice daily and all customers and fall back over a period of 5 minutes.
At this point, the edge router log appears:
invalid sequence number
mini: 138,137
received: 138135
discarding packet: MD5 authentication failed
source: IP hub.
After 5 minutes return to normal functioning and becomes about 8 hours so, then the problem returns.
-
the second concetrador has no customer problem fall but only on the OSPF if we leave the forced interface 1GB / s
-
concetrador teceiro also has fall customer problems but rose only OSPF when Colomos to communicate via ethernet interface and edge place a Rj45 GBIC of mikrotik.
What we try to do:
Update all CCRs to latest stable release
Change the CCRS for new CCRs backups
None of this funciconou.
Only what worked:
We put a switch between the edge and the crs 226 model concetradores communicating with 10GB / s and concentrators communicating with the switch for ethernet interface.
Does anyone have any idea what can be accepted as the ccr1072 communication via 1GB / s? Also because I have internet link running at 1 GB / s usually it.
