Visula route

Border leaf is set to 254, so that the default routes learnt from external neighbors are always preferred over the locally configured static route.

This will ensure that the default route is withdrawn when the interface goes down. This is automatically done if a

To the DC edge router is often called U-shape. By default, the border leaf when using default route configuration according to option 1 (default route injection for all VRF with default-information originate always configured under the VPNv4/6 address family) injects the default route in the fabric independent if the external link towards the DC edge router is down or up. In U-shape topologies this could cause blackholing for certain flows, as the traffic sourced on the leaf switch is hashed along the two default routes (ECMP) injected by the two border leaf nodes. Cisco NX-OS version 7.2(0)D1(1) or 7.2(0)N1(1) or later is required on the border leaf as this software version supports the U-shape topology. The DCNM 7.2(1) with the V3 POAP templates (for example, Fabric_N5600_N6K_BorderLeaf_v3) provides the required configuration. The border leaf POAP template provides the required configuration with the specific route-maps to avoid blackholing as shown below. ip prefix-list default-route seq 5 permit 0.0.0.0/0 le 1ipv6 prefix-list default-route-v6 seq 5 permit 0::/0route-map DEFAULT-ROUTE-MODIFY permit 100 match ip address prefix-list default-route set local-preference 50route-map DEFAULT-ROUTE-MODIFY permit 1000router bgp 65000!Peering to the first RR neighbor 44.2.0.101 remote-as 65000 address-family ipv4 unicast send-community both route-map DEFAULT-ROUTE-MODIFY in next-hop-self address-family ipv6 unicast send-community both route-map DEFAULT-ROUTE-MODIFY-V6 in next-hop-self address-family vpnv4 unicast send-community both route-map DEFAULT-ROUTE-MODIFY in address-family vpnv6 unicast send-community both route-map DEFAULT-ROUTE-MODIFY-V6 in address-family ipv4 mvpn send-community both address-family ipv6 mvpn send-community both!Peering to the second RR neighbor 44.2.0.144 remote-as 65000 address-family ipv4 unicast send-community both route-map DEFAULT-ROUTE-MODIFY in next-hop-self address-family ipv6 unicast send-community both route-map DEFAULT-ROUTE-MODIFY-V6 in next-hop-self address-family vpnv4 unicast send-community both route-map DEFAULT-ROUTE-MODIFY in address-family vpnv6 unicast send-community both route-map DEFAULT-ROUTE-MODIFY-V6 in address-family ipv4 mvpn send-community both address-family ipv6 mvpn send-community both Note The route-map 'deny-default-route' as shown in the previous section is replaced by the route-map 'DEFAULT-ROUTE-MODIFY'.

Notation Enables the display of route tag values in dotted-decimal format. route-tag notation To enable the display of route tag values in dotted-decimal format, use the route-tag notation command in global configuration mode. To disable this functionality, use the no form of this command. route-tag notation dotted-decimal no route-tag notation dotted-decimal Syntax Description dotted-decimal Enables the display of route tag values in dotted-decimal format. Command Default Tag values are displayed as plain decimals. Command Modes Global configuration (config) Command History Release Modification 15.2(2)S This command was introduced. Cisco IOS XE Release 3.6S This command was integrated into Cisco IOS XE Release 3.6S. 15.2(4)M This command was integrated into Cisco IOS Release 15.2(4)M. Usage Guidelines Configure the route-tag notation command to display route tag values in dotted-decimal format. When you configure this command, route tags are displayed as dotted decimals, irrespective of whether or not the route tags were configured as dotted decimals. Examples The following example shows how to configure the route-tag notation command: Device(config)# route-tag notation dotted-decimal Related Commands Command Description eigrp default-route-tag Sets a default route tag for all internal EIGRP routes. match tag Filters routes that match specified route tags. set tag (IP) Sets a tag value for routes. show ip route Displays contents of the IPv4 routing table. show ipv6 route Displays contents of the IPv6 routing table. show route-map Displays information about static and dynamic route maps. show route-tag list Displays information about route tag lists configured on the device.
