Further, there is a "peer gateway" feature with vPC, that allows both vPC peers to route traffic going to the HSRP vMAC, its on local MAC, or the local MAC of the vPC peer. Configuring the peer-gateway feature needs to be done on both primary and secondary vPC peers and is non-disruptive to the operations of the device or to the vPC traffic. vPC peer-link, in easier sentence to understand (at least for me), is to tell an NX-OS device who is it's neighbor. and ping result from sw1 to sw2 On 08/09/2013 03:52 PM, Christian Kildau wrote: > Hi Cisco-NSP, > > we're having some very strange issues while adding HSRP to our Nexus 5020 where both HSRP peers are up, but don't recognize each other, thus causing some issues.

In a Nexus 7000 Vpc environment, how can I form a layer 3 adjency between the two switches. 2(0)D1(1) (only on F2e and F3 modules) you can enable the layer3 peer-router. feature vpc vpc domain 1 peer-switch role priority 100 peer-keepalive destination 192. Here i want to explain, how to create a double-sided vpc in an enterprise environment. What is vPC. the built in vPC loop avoidance mechanism if the final destination is behind another vPC. interface port-channel30. Sorry for this pure Cisco Q here, have also posted to Cisco forum, but maybe anyone here knows better/faster. 23 Cisco Nexus - NX-OS 정리 Part 12 (vPC: Peer-gateway). For your first question, enable 'peer-gateway' under the VPC domain settings. 11 source 192. Figure 13-5 shows the complete, redundant setup where we have Active FW-1 and Passive FW-2 connected to Service Leaf switches Leaf-102 and Leaf 103 by using HSRP as an FW redundancy and vPC domain for Leaf switch redundancy. In the above figure, 7K1 will program MAC2 (MAC address of interface VLAN 10) in its MAC table and set G flag for this MAC address. ⑦vPCピアリンクのダウン時に、Primaryスイッチがダウンするという二重障害が発生してもSecondaryスイッチが正常に動作するための設定。 (config-vpc-domain)# auto-recovery. Everything is working fine and the VPC is formed ok (see show vpc output below) without any inconsistencies listed. Peer-gateway allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer allowing vPC peers to forward traffic. The rumors of this IT mega-merger have been swirling and were in full force this week. VPC Peer-Link : The vPC peer link is the link used to synchronize states between the vPC peer devices. This feature enables local forwarding of packets without the need to cross the vPC peer link. With core Nexus VPC peers, it is also recommended to set 'peer-switch' under the VPC domain settings and set their STP priorities for VPC vlans to the same values. vpc domain 1 peer-gateway peer-switch ip arp synchronize delay restore 120 graceful consistency-check auto-recovery auto-recovery reload-delay 240. Does anyone know how I can do this from Canada, preferably without a specify remote vpn gateway peer vpn server ip VPN?. So even if sh vpc command shows that everything is OK, it is not! vPC domain. vPC is a vastly inferior product to SMLT (nortel/avaya), which has been around for about 8 years now. Some applications may consider the Source ethernet mac address of the frame to be response to the ARP request instead of the Actual Source MAC in the ARP reply field. interface Ethernet1/1 switchport switchport mode trunk channel-group 1001 mode active no shutdown. You can make services available privately. 20 delay restore 150 peer-gateway auto-recovery ip arp synchronize ipv6 nd synchronize Configure the secondary IP address on the loopback. vPC status Id Port Status Consistency Reason Active vlans 1 Po1 up failed Global compat check 500,519,599. It keeps the forwarding of traffic local to the vPC peer device and avoids use of the peer-link (by not bridging the traffic to the other vPC peer device). This video is unavailable. Enable the vPC Peer-Gateway feature on the Nexus switches. Peer status : peer adjacency formed ok. Use Virtual Network to extend your on-premises IT environment into the cloud, like you set up and connect to a remote branch office. vPC peer-gateway is a gateway MAC localization mechanism, resulting in both vPC peers acting as the active gateway for packets addressed to the other peer device gateway MAC. The feature vpc must be enabled before this module can be used If not using management vrf, vrf must be globally on the device before using in the pkl config Although source IP isn’t required on the command line it is required when using this module. Here is the link to the Config Guide. delay restore 150. The feature is needed when certain storage/load balancing vendors break RFC rules by ignoring the ARP reply by an HSRP active router and reply directly to. The vPC peer-gateway capability allows a vPC switch to act as the active gateway for packets that are addressed to the router MAC address of the vPC peer. Peer-Gateway: The VPC peer-gateway allows HSRP routers to accept frames destined for their vPC peers. Peer gateway is a feature which was developed to support network devices which use non-standard layer 2 packet forwarding in a vPC environment.
