I have above scenario where I got public IP subnet got from ISP 74.100.100.0/23 and i have configured eBGP and iBGP as you can see in diagram, I have configured those Public IP in HSRP my LAN side. ISP sending BGP default route to us.

BGP config

router bgp 3xxxx8
  router-id 192.168.255.20
  log-neighbor-changes
  address-family ipv4 unicast
    network 74.100.100.0/23
  neighbor 74.1.1.69
    remote-as 1xxxx2
    timers 10 30
    address-family ipv4 unicast
      send-community
  neighbor 192.168.255.19
    remote-as 3xxxx8
    update-source loopback0
    address-family ipv4 unicast
      next-hop-self

HSRP config

interface Vlan100
  hsrp version 2
  hsrp 101
    preempt
    priority 110
    ip 74.100.100.1

At this point everything working great! now i have requested for more public IPs so ISP provided new public pool 74.200.200.0/23 and i have config it here like following.

BGP config (new subnet)

  router bgp 3xxxx8
      router-id 192.168.255.20
      log-neighbor-changes
      address-family ipv4 unicast
        network 74.100.100.0/23
        network 74.200.200.0/23
      neighbor 74.1.1.69
        remote-as 1xxxx2
        timers 10 30
        address-family ipv4 unicast
          send-community
      neighbor 192.168.255.19
        remote-as 3xxxx8
        update-source loopback0
        address-family ipv4 unicast
          next-hop-self

On HSRP side ( i have divided /23 in two /24 subnet to isolate traffic)

subnet 74.200.200.0/24

interface Vlan101
  hsrp version 2
  hsrp 101
    preempt
    priority 110
    ip 74.200.200.1 

Now HSRP working fine, but somehow i can't ping 74.200.200.1 from outside. Look like something is missing in route table somewhere. I have announce public subnet on OSPF like following.

interface Vlan101
  no ip ospf passive-interface
  ip router ospf 100 area 0.0.0.0

I did clear ip bgp on my peers also. In HSRP i divided /23 subnet in /24 so do you think i should use network 74.200.200.0/24 in BGP config?
