Is it possible to issue eigrp leaking routes on catalyst 6500 running IOS 12.2-33SXI9 on gigabitethernet interfaces? or is there another way to acomplish this?
View 10 RepliesI have a 3560 with IP base that is acting as a true EIGRP stub router today. It advertises local routes to the upstream service provider router and receives a default route.
Now I want to connect a 3900 ISR as a voice gateway. The 3560 does not seem to be advertising any routes to the 3900. Ok the EIGRP stub doc says this:
Only specified routes are propagated from the remote (stub) router. The router responds to queries for summaries, connected routes, redistributed static routes, external routes, and internal routes with the message "inaccessible." A router that is configured as a stub will send a special peer information packet to all neighboring routers to report its status as a stub router.
# Any neighbor that receives a packet informing it of the stub status will not query the stub router for any routes, and a router that has a stub peer will not query that peer. The stub router will depend on the distribution router to send the proper updates to all peers.
I guess I don't understand why the stub advertises local routes to the upstream ISP router but does not seem to advertise routes to the 3900. Does the stub identify the ISP router as the distribution router somehow, thus differentiating it from the 3900? If so, how is this done?

If a router receives EIGRP (AD90) routes, and is configured to redistribute thoes routes into BGP(AD20), why does the RIB show only the incoming EIGRP routes and not the redistributed bgp routes? Are redistributed routes considered for RIB entry in the router that is doing the redistribution
View 2 Replies View RelatedIs there a way in EIGRP to prefer external routes versus internal routes. EIGRP always picks up internal routes as long as they are available, no matter if external routes have better metric. Our Scenario is that we have DMVPN hub and spoke topology running EIGRP 101. The Core routers also on EIGRP 101 prefer EIGRP 101 routes. We have the new MPLS network running BGP and redistributing these BGP routes into EIGRP 101. The core routers prefer EIGRP 101 routes (internal) to redistributed BGP (external) routes.

View 2 Replies View RelatedI have a scenario which is fairly common - certain servers are accessed from the internet via a Load Balancer, and since seeing true client IP is a requirement, the return traffic path must go back through the load balancer. However, I do not want to route all traffic via the load balancer for obvious performance reasons. Internal traffic should be routed directly by the Layer 3 switch, which has a default route of a Firewall.
My plan is to use a VRF for the load balancer and any applicable servers, which works fine. But now I need to join the VRF's routing table with the switch's GRT (global routing table) so that internal traffic works. What is the best way to do this? For scalability reasons I'd like to avoid static routes and I see many examples using BGP, but in this case it seems overkill since everything is on a single logical switch. Can I use OSPF instead? Or a different method? The Supervisors will be 2Ts, so IOS 15.0 will likely be running.
Is there a command available on the 6500 that I can use to see what prefixes it is advertising directly to a neighbor?
The diagram is detailed and complex, but the simplest problem statement is that it doesn't look like my 6500 distribution switches are advertising certain prefixes to one of the 6500 access switches. I don't know whether this is an issue of the distribution switches not sending the prefixes down to the access layer (they should be; the route originates on a different set of access switches) or my access switch is dropping the prefixes. I don't see them in the topology table at all.
If the prefix isn't being advertised, I need to troubleshoot the distribution. If it is and it's being ignored, I need to troubleshoot the access. There are no obvious conditions that would prevent the access switch from getting the prefixes -- interfaces aren't passive, no distribute lists at work, everthing in the same AS, I have neighbor relationships (and I am getting other prefixes over these links, and these prefixes are being advertised to other access switches), auto-summarization is off, split horizon is still on . . .
I have a very detailed diagram of all of the metrics and links and I don't see any reason why my access switch shouldn't be getting the prefixes. 6509 chassis, dual sup 720 3B, 12.2(33)SXI4a advanced enterprise services IOS.
Four 6500 connected to each other to form a full mesh. Switches 4 and 7 is running eigrp. A question came up, why didnt it have eigrp on SW 2 & 3 ? Will it still be redundant if link between SW3 and SW4 is removed? If redundancy is working, SW3 should be able to find its way to SW4 via SW7 or SW2, yes?
The config looks:
SW4 eigrp
router eigrp 100
network 192.168.0.0
redistribute static
auto-summary
[Code]....
Recently, the eigrp was configured to SW 2 and SW 3 as well, it included the “redistribute static” statement. The route for SW2 and SW3 now has the VLANs, 51 or so. Sent ping from a PC to VLAN1 IP of SW3, then link between SW3 and SW4 was disconnected, network connectivity went down for about 20secs, and ping came right back. Thought it was a success. All of a sudden, outside connectivity was lost. Ping within the LAN was successful, but no internet connection.
The eigrp on SW2 and SW3 was removed, and the internet connection came back up. The initial concern was that although there is physical redundancy in place, the other routes may not be known. Hence, eigrp configuration has been attempted for SW2 and SW3. Perhaps the “redistribute static” should have never been configured on SW2 and SW3, SW7 does not have the “redistribute static” statement anyway.
Without eigrp running on SW2 and SW3, does it still have redundancy? For what it’s worth, SW4 and SW7 are both VTP servers. With the current configs, does it still have redundancy? Link redundancy was never tested; it always has been assumed that it works. Later today, with it’s current config, the link redundancy will be tested.
I am observing some strange behaviour related to the routing table, almost all external routes and some inter-area routes are getting refreshed every 10 seconds.
I am getting more than 1000 entries after running 'sh ip route | i 00:00:0', these external routes are being advertised by a neighbor 6500 which redistributing these static routes.

I have an issue with my setup of a 6500 switch (12.2(33)SXI9).We have a 6500 switch with several VRF's. For a certain VRF I would like to redistribute a static route in EIGRP. After doing so I don't see the static route on my eigrp neighbor.
This is a overview of my config. I'm basically redistributing only my static route for this vrf in eigrp.
I found a similar case in which the solution was adding a metric to the static route. (eg. redistribute static route-map static-eigrp-pp metric 10000 100 255 1 1500). But the strange thing is that we don't have this issue on a similar machine (same IOS, same config setup). [code]
I have a pair of data center core 6500 is running a single EIGRP AS with the standard core redundant cross connects. Recently an SVI sub net was expanded from a /24 to a /23 and dropped out of the EIGRP routing table. Subsequent trouble shooting lead to the router id being one using an IP address that is no longer active IP address.
Reviewing old configurations I found, that year ago, the ip address used for the EIGRP router-id (10.100.106.3) was removed from the active interface and changed but the EIGRP router-id was not updated. The switch has not been rebooted since, no loop back is configured and there is not a higher IP configured on an active interface. Reviewing documented material on it, I cannot find anything specific on this condition but do see in the discussions on duplicate IDs, that new route updates can be a problem. I know how to update the router id but I am looking for confirmation on what would be the impact when I add a new loop back and manually configure the router-id under the EIGRP process with the new loop back IP.
My assumption is an EIGRP update and route re convergence with the standard 90 seconds of outage. How to confirm this is assumption is correct? I have no test bed to find out myself without doing this on the active cores.

1. We now have SupA & SupB in the chassis, due to some mistake we have same IOS version but different feature set on them, although we configured redundancy mode sso, in the "show redundancy" we see Operating Redundancy Mode = rpr due to Software mismat, we now need to fix them as same feature set image, if I use "copy sup-bootdisk0:/xxxx slavesup-bootdisk0:/xxx", then write memory, does this cause any service/network interuption?
Available system uptime = 1 year, 1 week, 4 days, 9 hours, 21 minutes
Switchovers system experienced = 2
Standby failures = 0
Last switchover reason = active unit removed
[code]....
2. We did a failover test with this status, found that if we triggered supervisor failover, all modules will reload thus the services if interupped. How about after we make the Operating Redundancy Mode as sso, will this behaviour shows again? Or a stateful failover will happens, then modules no need reload?
3. We are using OSPF as our L3 routing protocol, after reference to the configuration, nsf should be enabled, we want to ask in the OSPF-domain nsf should be configured in all OSPF-enabled router or only 6500 which have dual-sup?
4. We also found that the interfaces(3 * Gig & 2 * TenG) in Standby supervisor cannot be use even enabled & configured, is it because we are running rpr mode now or will be the same even change to sso? Before customer have some older supervisor in 6500 non-e chassis, and they can use the standby supervisor interfaces as traffic forwarding, they use rpr-plus mode before, how about in sso mode?
"How to display the EOBC error counters in the Catalyst 6500 series switches and a definition of the EOBC interface" document here on support forum stays that The Ethernet Out of Band Channel (EOBC) is a half duplex channel that services many functions, which include the Simple Network Management Protocol (SNMP) and the packets that are destined for the switch.
Previously i were thinking that EoBC used only for SCP and SLP protocol. In addition i found other article (but not on cisco site, heh) where stays that The Results bus is a control plane, while the C (EoBC) bus is more of an "admin plane", thus you will never see data packets (such as CDP, SNMP, etc.) going over the R or C bus.
So there is a big contradiction between those two statements. How to prove one of those and if first one right, what meaned under the packets that are destined for the switch in it? SCP and SLP or other traffic as well?
I am migrating services from SUP720-3B to VS-SUP2T-10G= and moving to a VSS configuration between a pair of Cat6506 distribution layer switches. I need to enable QoS on these switches, primarily to trust dscp and also to prioritise voice traffic. The autoqos feature works for some ports but does not work on port-channel interfaces and port-channel member interfaces. How can I apply the qos settings for these interfaces in line with what auto qos would normally provide. My line cards are as follows:

The diagram below is the configuration we are looking to deploy, that way because we do not have VSS on the 6500 switches so we can not create only one Etherchannel to the 6500s.Our blades inserted on the UCS chassis have INTEL dual port cards, so they do not support full failover.
Questions I have are.
- Is this my best deployment choice?
- vPC highly depend on the management interface on the Nexus 5000 for the keep alive peer monitoring, so what is going to happen if the vPC brakes due to:
- one of the 6500 goes down
- STP?
- What is going to happend with the Etherchannels on the remaining 6500?
- the Management interface goes down for any other reason
- which one is going to be the primary NEXUS?

I understand that my questions seems to be rather strange cos supervisors is rather old (Sup1A especially). But i am interested in understanding what puprpose were in production SUP32. I cant find out enough differencies between Sup1A with MSFC2 and Sup32 to understand what reasons lead to deploying new sup in none fabric supervisor series.
Both supervisors have same perfomance - 15Mpps and have limitation on backplane bandwith of 32 Gbps (cos both use swithing bus), both supervisors equipped with MSFC2 and etc. Differencies i found:
SUP 32 have 10Gbe ports support (but this seems to be doubtful enhancement - with it perfomance GE ports seems to be more appropriate technology isnt it?) SUP1A equipped with PFC, SUP32 with PFC3BSUP32 deploys CEF (what is benefit of CEF if perfomance same?)
On a Catalyst 6500, we configured a SPAN session with VLAN 300 as a source. We configured the session bi-directional ("both" keyword). We connect a sniffer on the SPAN destination port.
Strangely enough, we only see the traffic from the VRF to the firewall, but not the reverse traffic ! What can be the problem ?
Are there any best practices for preventative maintenance on Catalyst Chassis switches. Looking to build a PMI schedule for a customer. Or is there evidence not to perform it at all. Things like re-seating line cards, cleaning fan exhausts, etc.

If I do a netdr capture I can see ERSPAN traffic sourced from the Nexus reaching the C6500, but there doesn't appear to be anything sent out the ERSPAN destination inerface (Gi4/6) and there's nothing being received by the probe connected to that interface. I know the traffic seen with netdr is definitely the ERSPAN traffic sourced from the Nexus as I've changed the TTL and DSCP values within the monitor session on the Nexus and can see those changes reflected on the C6500 netdr capture. The attached is a screen grab of the show netdr capture started with debug netdr capture soure-ip-address 192.168.2.133.
When I look at the interface I see it shown as up/down (monitoring), but no output or counters clocking up. If I run a local SPAN session on the C6500 it works fine.
I've tried changing the destination IP address from that assigned to the C6500 Loopback interface to an IP address assigned to a physical interface, but that still doens't work.
