Hi guys.
I'm hitting wield issue with OSPF via DVTI VPN.
Whenever VPN established I got OSPF routing tables populated on both sides. in some different time (it looks like after VPN key renegotiation?) I see tunnel is up from both sides (HUB and spoke) but HUB routing table missed routers from spoke but still keeping them in OSPF topology table and database. So. outputs bellow:

After I manually reset that VPN tunnel (doesn’t matter side) everything back again (routing tables populated at both sides) and in some e time (I guess after second, third and so on... VPN negotiation. I decrease VPN renegotiation down to 3 hours for both sides and after first renegotiation OSPF always successfully installs spoke routes to hub routing table) routes disappears from HUB routing table but still present in HUB topology table.
Any thoughts?
Thank you.

Hi guys.
I have network like:
nexus 5k (core&distribution) -VPC53, po53 -> enterasys access switch stack#53 in vlan 53, lag.0.1 same nexus 5k (core&distribution)-VPC54 po54 ->enterasys access switch stack#53 in vlan 53, lag.0.1
switch 53 ports ge.1.47-48 are lagged to lag.0.1 and they uplinks to nexus po53, VPC53, rest of ports in access mode, vlan 53 members switch 54 ports ge.1.47-48 are lagged to lag.0.1 and they uplinks to nexus po54, VPC54, rest of ports in access mode, vlan 54 members
situation as follow:
whenever users interconnect (I believe by mistake) to neighbor desk ports one port in vlan 53 another in vlan 54, nexus detects this look at STP shutdown. As results !90 users lost access. Log file records like: ++++++++++++++++++++++++++
079949: Oct 5 15:35:35.183 EST: %SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 53 on Port-channel54 VLAN54. 079950: Oct 5 15:35:35.183 EST: %SPANTREE-2-BLOCK_PVID_LOCAL: Blocking Port-channel54 on VLAN0054. Inconsistent local vlan.
CAONTO1Y05-SW-01#sh spanning-tree blockedports Name Blocked Interfaces List -------------------- ------------------------------------ VLAN0054 Po54
Number of blocked ports (segments) in the system : 1 ++++++++++++++++++++++++++
So. Question.
If I enable BPDUguard at sw53&54 access ports is it help me to shutdown just one access port whenever bpdu packet hits to it? I did it many time against of interconnecting two ports at the same switch & switch stack but right now there is two stacks can reach each other via nexus.
Thank you.

Hi guys.
I need to implement following scenario:
When inside computer 192.168.172.20/28 opens connection to 192.168.172.1/28 port 777/tcp (192.168.172.1 - is cisco router) connection will rewrite source to 192.168.172.1/28:1025-65535/tcp and destination to 10.5.8.7:3389/tcp
returning packets from 10.5.8.7:3389/tcp needs to rewrite source 192.168.172.1:777/tcp and destination 192.168.172.20/28
Another words for security requirements RDP to 10.5.8.7:3389/tcp can be accessible from 192.168.172.1/28 only.
Subnet 192.168.172.16/28 isn't advertised and locked (some kind of DMZ :) to 10.5.8.0/24
Could somebody suggest?
Thank you.

hi guys.
I have HUB in head office and many small offices connected via DVTI VPN (IKEV2) to HUB.
yesterday one office DVTI IKEV1 (t5.1ko.org) was decommissioned (router power off and internet line has been removed), but I still see router t5's session. Weird thing is PHASE 1 (red bellow) record exists. PHASE 2 doesn't exist (blue bellow):

i guys.
History:
I got notification from IT security team that one computer in subnet 10.244.244.0/26 has a malware on it (it's opening multiple connections to 192.42.119.41 detected by IPS as malware ). I need find out that computer private IP.
Subnet 10.244.244.0/26 PATing to public IP x.x.x.x
firewall logging looks like:
logging enable logging buffer-size 1048576 logging monitor notifications logging buffered notifications logging trap notifications logging history notifications logging from-address di@di.di logging recipient-address netops@ar.ar level emergencies logging facility 18 logging queue 0

access-list name data_access_in assigned to interface where ip from subnet 10.244.244.0/26 is.
I added wery first ACE permitting any connections from 10.244.244.0/26 to 192.42.119.41:80/tcp
access-list data_access_in line 1 extended permit tcp object data-network host 192.42.119.41 eq www log debugging
Whenever I run test by packet-tracer:
TDI04-DI0-FW01(config)# packet-tracer input data tcp 10.244.244.30 4455 192.42.119.41 www det
ACE hits increased (red bellow):
TDI04-DI0-FW01 (config)# sh access-list data_access_in | i 192.42.119.41 access-list data_access_in line 1 extended permit tcp object data-network host 192.42.119.41 eq www log debugging interval 300 (hitcnt=2) 0xfd11a8a6 access-list data_access_in line 1 extended permit tcp 10.244.244.0 255.255.255.192 host 192.42.119.41 eq www log debugging interval 300 (hitcnt=2) 0xfd11a8a6 TDI04-DI0-FW01 (config)#
but I don't see packet registered by syslog @ 172.16.63.145 (greed above).
Syslog consists only this:
Sep 28 09:54:52 10.4.4.3 10.4.4.3 %ASA-5-111008: User 'as-admin' executed the 'packet-tracer input data tcp 10.244.244.30 4455 192.42.119.41 www detailed' command.

Could you help me out?
Thank you.

my side router is Cisco 877W + latest 3 years old image: C870-ADVIPSERVICESK9-M), Version 15.1(4)M10
other side is Ubiquiti access point. I don't know model because I don't have access to it.
still question why and (how to improve) my router shows:
Packets Output : 60117
Data Retries : 20044
so ~30% packets retransmitted.
Maybe I have setup wrong speed on wireless interface.
