使用TextFSM分析IOX XR的show命令

Question

尝试使用textFSM解析此输出，仅捕获IPV6地址和前缀（最后一列）

  BGP router identifier x.x.x.x, local AS number 22773
  BGP generic scan interval 60 secs

使用此TextFSM模板，但它只会转储IP地址

  Value NEIGHBOR (\S+)
  Value SPK (\d+)
  Value AS (\d+)
  Value MSGRCVD (\d+)
  Value MSGSENT (\d+)
  Value TBLVER (\d+)
  Value INQ (\d+)
  Value OUTQ (\d+)
  Value UPDOWN ((\S+(\s\S+)*))
  Value PFXRCD (\S+)


  Start
     ^${NEIGHBOR}           

^${SPK}\s+${AS}\s+${MSGRCVD}\s+${MSGSENT}\s+${TBLVER}\s+${INQ}\s+${OUTQ}\s+${UPDOWN}\s+${PFXRCD}->；记录

不知道为什么它不会显示IP地址+其他字段

此show命令将只在一行上转储每个IP地址，而在另一行上转储其余IP地址，这与屏幕大小等无关

IPv6地址前面的行缺少\s+：

Value NEIGHBOR (\S+)
Value SPK (\d+)
Value AS (\d+)
Value MSGRCVD (\d+)
Value MSGSENT (\d+)
Value TBLVER (\d+)
Value INQ (\d+)
Value OUTQ (\d+)
Value UPDOWN ((\S+(\s\S+)*))
Value PFXRCD (\S+)

Start
  ^${NEIGHBOR}
  ^\s+${SPK}\s+${AS}\s+${MSGRCVD}\s+${MSGSENT}\s+${TBLVER}\s+${INQ}\s+${OUTQ}\s+${UPDOWN}\s+${PFXRCD} -> Record

输出：

NEIGHBOR, SPK, AS, MSGRCVD, MSGSENT, TBLVER, INQ, OUTQ, UPDOWN, PFXRCD
