Symptoms: A BGP VPNv4 table may contain paths that may be imported from deleted BGP table
entries or from table entries that have a different prefix from the importing prefix.
An example of a path from a deleted BGP table entry is as follows:
Router# sh ip bgp v v vpn2 192.168.0.0
BGP routing table entry for 200:2:192.168.0.0/32, version 52
Paths: (1 available, best #1, table vpn2)
Advertised to non peer-group peers:
10.4.1.2
2 100, imported path from 2829:2829:185404173:11.13.11.13/-53
10.1.1.2 from 10.1.1.2 (10.1.1.2)
Origin IGP, localpref 100, valid, external, best
Extended Community: RT:1:3
The entry that this path is imported from has been removed from the table and its memory contents
contain an incorrect pattern. When the incorrect pattern is displayed as a prefix, it appear as
“2829:2829:185404173:11.13.11.13/-53”.
A mismatched prefix appears as follows:
Router# sh ip bgp v v vpn2 192.168.0.0
BGP routing table entry for 200:2:192.168.0.0/32, version 54
Paths: (2 available, best #1, table vpn2)
Flag: 0x820
Advertised to non peer-group peers:
10.10.10.10 10.20.20.20

10.4.1.2 from 10.4.1.2 (10.4.1.2)
Origin IGP, localpref 100, valid, external, best
Extended Community: RT:1:2
2 100, imported path from 200:2:172.16.0.0/24
10.1.1.2 from 10.1.1.2 (10.1.1.2)
Origin IGP, localpref 100, valid, external
Extended Community: RT:1:3
This BGP VPNv4 table entry is for prefix 192.168.0.0/32 but it shows that a path is imported from
172.16.0.0/24. This situation occurs when a path has a link to a deleted BGP table entry, and then
the memory for the deleted entry is reused for a new table entry of which the prefix may not match
with the importing entry.
Conditions: These symptoms are observed when you enter the maximum-paths import number
command in router BGP address-family IPv4 VRF mode. The number argument indicates the
number of paths to import from one VRF to another.
Workaround: Remove the maximum-paths import number command from the router BGP
address-family IPv4 VRF mode.
