Inter Vlan Routing dropping Ping
I have an issue with inter vlan routing. When I ping 172.16.37.7(SW3) from R1 I get between 40 to 50 percent success rate. I'm able to ping 172.16.10.0 network from R1 without any dropping
have the following Connections:
R1 connect to SW1 with switchport dot1q allowing vla 10 and 37.
R1 Config:
SW1 Config
SW1 Connects to SW3
SW1 config to SW3
SW3 Vlan 37 IP
is any reason why i dropping pings?
have the following Connections:
R1 connect to SW1 with switchport dot1q allowing vla 10 and 37.
R1 Config:
interface Ethernet1/1 no ip address full-duplex ! interface Ethernet1/1.10 encapsulation dot1Q 10 ip address 172.16.10.6 255.255.255.0 ip ospf hello-interval 5 ! interface Ethernet1/1.37 encapsulation dot1Q 37 ip address 172.16.37.6 255.255.255.0
SW1 Config
interface FastEthernet0/6 description router_1_connection switchport trunk encapsulation dot1q switchport trunk allowed vlan 10,37 switchport mode trunk switchport nonegotiate duplex full end
SW1 Connects to SW3
SW1 config to SW3
interface FastEthernet0/19 switchport access vlan 37 switchport mode access end
SW3 Vlan 37 IP
interface Vlan37 ip address 172.16.37.7 255.255.255.0 end
is any reason why i dropping pings?

RouteMyPacket Member Posts: 1,104Real equipment or no? L2 switches? You're a CCNP right? What are your thoughts?Modularity and Design Simplicity:
Think of the 2:00 a.m. test—if you were awakened in the
middle of the night because of a network problem and had to figure out the
traffic flows in your network while you were half asleep, could you do it? -
amb1s1 Member Posts: 408Real Equipment, routers are 2600 and switches are 3550s. yes ccnp. My first thought was that it was an issue with duplex miss match, but after i check all the interfaces i discard that as a problem. I see not collision on the interfaces.

Jackace Member Posts: 335What does the config look like on SW3 for the port connected to SW1? Do you have the default gateway set on SW3? What does the rest of the config look like on each device? What's the arp table and mac table look like on all 3 devices? Are both tables stable or do you see entries coming and going or changing sporadically?

fredrikjj Member Posts: 879If it's 50% success rate maybe the routing is messed up and you are load balancing between two interfaces where only 1 reaches the destination.

joeypants05 Member Posts: 10 ■□□□□□□□□□Is spanning tree solid between the switches or do you see the states changing frequently? Are there any errors on the interfaces along the path? Did you check the speeds of all interfaces to make sure they match up?

Fitzi Member Posts: 40 ■■■□□□□□□□Check your ip is not assigned to another interface in addition to the one you are using. If this is not the case clear the interface counters and check for errors, otherwise try alternate cables.

Yes based on the configs and the snipets you have posted it doesn't look like you have the encapsulations right or there was some copy/paste issues. You also mention a router 6 in the mix and I see ports on your SW1 that are forwarding traffic on vlan 37, but we don't know how all these devices are connected and their configs. -
networker050184 Mod Posts: 11,962 ModSo are you showing us the actual configs or what? Kind of hard to tell whats going on here. Some are showing 3000 some 37.An expert is a man who has made all the mistakes which can be made.

I see CRC errors. I thought I check that yesterday. I check for a faulty cable, double check the duplex on both. I clear the counter before showing this input. -

Just did this and it went to 10 and full duplex on both side r6 e1/1 and switch1 f0/6, but still dropping pings and i see crc errors.

What model router is R6?An expert is a man who has made all the mistakes which can be made. -

What model router is R6?
I check this article about 802.1q support on 2600. I see that NM-4E is not support it on 12.2. i have 12.4 on this router. I did a search to see if dot1q is support it on 12.4, but could not find any info on that. I never encounter a technology not support it, but still able to type the command.
